# 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

**tab when you add**

*Basic***to the form.**

*Form Elements*Once you've added the **Input Table**, __select 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

**to the form.**

*Form Elements*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.

CSBRAGAI'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.

jimwhiteAm 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.

lansingpartyI 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?

ZacharyRichardsI 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

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

It is the attendance sheet here: https://form.jotform.com/63495321047152

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?

Thanks!

jannyfer.chuaHi, 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?
