How to Perform Form Calculation in the Matrix Field?

It is now possible to use the Matrix field to perform form calculation.

Here in our example, we will set the matrix field similar to a survey questionnaire with ratings or value on them, we will calculate the total rating using the Form Calculation widget. You can follow the steps below on how to do that.

In Version 4.0, we call the Matrix Table from Version 3.0, Input Table. It can be found in the Quick Elements section of the Basic tab when you add Form Elements to the form.

Once you've added the Input Tableselect an input type from its properties (cogwheel icon). From the same Fields tab of the Input Table properties, you will be able to set row and column headers.

After constructing the table, you now need to set calculation values for each of its cell (matrix sub-field). To do that, go to the Options tab and enter the values in the provided text area for calculation values following this simple rule, "Separate each column with a comma and each row with a new line."

In the example above, 4 Rows means 4 lines and 4 columns means 4 values separated by a comma.

Note: Choosing a different input type for the table, like a text box or number text box, if you want your respondents to define values for each cell, will not require you to set calculation values.

To get the total value of the selected cell(s) on the table, you will use the Form Calculation widget from the Widgets tab when you add Form Elements to the form.

To perform the calculation, you need to add the input table to the calculation area of the Form Calculation widget.

Clicking the "Add Field" button shown in the screenshot above lets you add fields to the computation.

Adding an Input Table field will let you select which row (radio button) or cell (checkbox field) in the table is to be included in the computation. (This is also referred as matrix sub-fields.)

After selecting the matrix sub-field(s) and clicking Done, you will see the selected sub-fields of the input table in the calculation area of the Form Calculation widget. From there, you will be able to create your own formula to get a total value. The calculation pad on the right will surely help you with the simple to complex mathematical tasks.

    is there a way we can use the cell input value for the calculation? eg: for a cell that collects a number for total hours worked, can we use that value rather than a static value that I apply if the field is filled?

  • topprime

    Hey guys, how can i make it responsible?

  • topprime

    Hey guys. I need to make one of the columns read-only, how can i do it?

  • HuttonSafetyGroup

    Hey guys! Now that you've implemented the Multi-Type Columns in the Input Table (YAY!), would you be able to do a page like this for how to do calculations based on answers with dropdowns, etc? I may be over thinking it but it seems quite complicated.

    For instance, I want to be able to populate a "Describe below" box if someone selects an answer in one column that uses a dropdown, but also populate a different "Describe" box if they select a radio button answer, etc.


  • jorgemanriquetc

    How can I get a different answer in each row along the matrix?
    Thank you very much.

  • SilverOakDM

    I don't know how to word this question, but I can explain what I'm trying to accomplish.
    In column one, players input their values. Each value has a modifier. I want to be able to type "12" in column 1 and have column 2 automatically spit out the correct modifier value (1). Is there a way for me to program this?

  • justdawn

    how do i make it that you can only select certain columns for each row
    row one- the only options can be column 1 and 3
    row two the only options can be column 2 and 4

    How can this function be used using the "drop down" selection with more than one value can be selected?

  • artnilsen

    The answer to my comment below just gave me a link to this web page on which I had the "How to" question."
    As I understand it, I do not need a calculation. I just need to be able to move the contents of a field previously entered into one or more of the rows and columns in a table. Please clarify your response.
    Thank you.

  • artnilsen

    How can I set the value in a table cell (As an example: Row 1/Column 1) equal to a field entered above?

  • sellyon

    I have a table with 6 rows and 3 colums. The fields of the colums (radio buttoms) are : choice 1, choice 2, choice 3.
    Is it possible to limit the form to only one choice 1, only one choice 2, olny one choice 3, in the table ?

    Thank you

  • razana

    i only have 1 row and 1 column, how to widen the column? tQ


    I'm trying to total a column using the Form Calculation Widget and I don't know what I'm doing wrong.
    I can't seem to get the + sign after the added field and then the numbers are calculating higher than they actually are. I put in 10 and 10,000 is showing up in the calculation field.

  • jimwhite

    Am I able to have two separate calculations for one table? For example, I am using as a daily time sheet and have a column for regular hours worked (which is calculating correctly) and a column for overtime hours worked (which is only duplicating what is in the regular hours field). I am doing the formulas the exact same for each different column but not getting two separate answers.

    Can I make it so that each drop down option can only be used once?

    How can I delete a field and add a different field from the add field button?

  • KPWM

    I want to assign values to each question in my matrix, but I don't want the person filling out the form to see the value. I only want to be able to see it. Is this possible?

  • lansingparty

    I am hoping to get some help here because I am sure this is possible and I am simply missing how to do this. This is a limo company with a few variables. Lets make it simple and say we have limoA, limoB, and limoC. Each of these limos have an hourly rate for Weekday, Friday, Saturday. How would I set this up so the customer could fill out the form select the day of the week, use a check box form to select what they want quotes on, then depending on the hours selected multiply the value by the hours?

  • ZacharyRichards

    I wanted to know if it were possible to create a calculation in the actual matrix.
    For example, a cell in the matrix equals a date that someone put in above the matrix.
    Is this possible

  • poudreriver

    I am trying to count how many checkboxes are checked in a matrix.

    It is the attendance sheet here:

    I am trying to figure out how I can set the value of each checkbox to 1. I know that I can insert 1, but I don't want that to show in the headers. If I hide the headers, then the months can't show. I need to be able to show the months across the top. Do you have any suggestions for how I an do this?


  • aysaquing

    Can I set condition on form matrix calculation? For example if column 5 as remarks says Best, the calculator will just compute all fields (rows) with best. Is that possible? Thanks.

  • jannyfer.chua


I have a set of 28 questions and 5 radio columns (Never, Rarely, Sometimes, Very often, Always).

a) How do I set values for each column and when they are selected, the values are added up? e.g. Never=1, Rarely=2, Sometimes=3, Veryoften=4, Always=5 
if Never is selectedx2, rarely x1, always x2 = the total is 14.

b) How do I set the 28 questions to calculate 4 different totals from the above columns. eg. Qs 1-7, 8-14, 15-21, 22-28 and then set a formula to only show the results for the highest total?

  • IDOEWebmaster

    How do I multiply the value of column 1 and column 2 and show the result value in the column 3 of the matrix table?

  • Communicaid

    ok, thank you for your help

  • Communicaid

    I've created a matrix question with dropdown list "yes" and "no" and I wwould like to add the values to the "yes"=1 and "no"=0.
    my question is: can I use the same role live above : yes1?
    what is the css code to hide the numbers?
    Thank you in advance for your help

    I have tried to output the sum of a matrix's fields multiple times. Every time I save the logic the fields are removed and all I am left with in my equations is the addition signs.
