I have a table in Acrobat 2017 form. There are 2 columns for payments to utility vendors. One for Gas One for Electric. What I am trying to do is total each column then sum the 2 column totals. I can create calculations for the 2 columns alright then sum the 2 totals, but it doesn't work like I want it to. The first column imports payments from our database, the second column payments have to be entered by our caseworkers. The data imports fine into tcolumn 1 of the table but does not calculate until I enter an amount in the second column then all of the calculations happen. If nothing is entered into the 2nd column no calculations happen so if the caseworker doesn't have a payment for column 2 all of the totals stay zero. Can this operation be done with the "Value is the sum" calculation or will I have to use Java Script to get it to work like I want it. I don't know how to write java script. Thanks.
