Calculate Values in the Input Table Through Condition

Last Update: March 8, 2017

Calculation is one of the basic feature with JotForm. You can either perform calculation using the Form Calculation Widget or through Update/Calculate condition.

In this guide, you'll learn how to perform calculation in the input table field (formerly known as matrix field) through update/calculate condition and output the result on a text box field within the same input table field.


Here's how:

1. Add the Input Table field in your form

2. In the top toolbar, click the  Settings menu. On the left side, select Conditions then the Update/Calculate Field

3. Create a condition that calculates the field whenever the Input Table field is filled.


If Input Table is filled, Calculate a field's value

4. Then click the ADD FIELD button to add the fields you want to calculate from the Input Table field.

Example: You can select the fields from the first 4 columns then add them, and then output the result on the 5th column. Check the animation guide below:

Here's a sample form with this condition:

If you want to perform calculation on the input table field with checkbox or radio button input types, here's a guide - How to Perform Form Calculation in the Matrix Field

I try to follow this - but your example looks nothing like the form I'm trying to create. The left sidebar is completely different!
My sidebar is "Form Elements"
So these instructions don't help me!
