I'm working on a form and am trying to sum the totals entered into four different fields.
Is this possible?
You don't need JS. Use this option in the Calculate tab and then select the fields you want to add up from the list:
Acrobat provides 3 different calculation method and any one of the three is capable of summing four fields.
You can use the "Field is the _______ of the following fields" and select "Sum" and then select the fields to be included in the sum. Just use the mouse to highlight the field name and press the space bar.
You can use "Simplified field notation" and enter the field names separated by the "+" operator if the field names contain no special characters or spaces in their names.
