Custom Calculation for Subtraction

[Alan Grzybowski]

I'm trying to create a form for subtraction but I'm not familiar with javascripts

Bump for this, I would like to know this as well.

Thank you for reaching out through our Community Forums!

Below is a sample script if you wish to subtract one or multiple fields from another field. The script should be placed on the field where you want to display the result. 
In this example, Text3 has the script to subtract Text1 and Text2. 

// Obtain the value from the first field
var v1 = getField("Text1").value;
// Obtain the value from the second field
var v2 = getField("Text2").value;
// Set this field value equal to the difference
event.value = v1 - v2;

You will change "Text1" and "Text2" to the names of the text fields that you have chosen. This will subtract Text1 from Text2.

Kind regards,
