I really appreciate your help on this. It's exactly what I was looking for...! I was using a different script that worked for the most part, but it failed to update the Cumulative total whenever the user changed a payment amount. Your script does update the total, so I'm a very happy camper.
The only thing I wonder is if it's possible to not show the Total value(s) on subsequent rows if no payment amount has been entered on active row (null) and/or if the payment field is blank on that row. For instance, when the form is first opened, I have 3 instances show up by default and this is what I see:
NOTE: ... = blank or null value
Period Payment Cumulative Payment
1. ... ...
2. ... $0
3. ... $0
If I then proceed to enter a payment amount in the first row, I get:
Period Payment Cumulative Payment
1. $500 $500
2. ... $500
3. ... $500
What I would prefer (if possible) is:
Period Payment Cumulative Payment
1. $500 $500
2. ... ...
3. ... ...
and/or something like this:
Period Payment Cumulative Payment
1. $500 $500
2. ... ...
3. $600 $1,100
4. ... ...
5. $9,500 $10,600
Please advise, and THANK YOU for your assistance thus far.
