How to conditionally sum up the values from a repeating section

Should be pretty straight forward. 

Here is a quick example. 

Control Layout:

Control Names & Settings: 

(single line text for currency input)

(yes/no for Approval) 

(calculated control for total money in all rows)

(calculated control for total money that has been approved - see below for formula)

Formula For 'Filtered' Calculation: 

(function(moneyValues, approvalValues){
  var approvedValues = [];
  for(var i = 0; i < moneyValues.length; i += 1) { 
    if (approvalValues[i]){
      approvedValues.push(moneyValues[i]);
    }
  }
  return sum(approvedValues);
}(someMoney, moneyApproved))‍‍‍‍‍‍‍‍‍

(note: at the bottom, you'll need to replace someMoney and moneyApproved with there NAMED CONTROL references as shown here:)

Results: 

This should get you to where you're trying to go, but please remember that you might want to think about implementing a third party library to handle the currency input checks and totaling due to how javascript natively handles floating point math!!!!!

I'm currently using currency.js much to my liking, but it takes a little bit to get used to how it handles things. You'll still need to probably create a validation rule to normalize the input for the currency (and to possibly restrict automatically or by way of validation) "what" passes as an acceptable numeric input, but as for totaling, it works fairly easily. 

Hope this helps! 

N M, first of all, I sure hope that is a picture of you!!! second, thanks for making the time to put together such an AMAZING reply! I appreciate the time and effort you put into this. THANKS!!

I'll give it a look see today.

it is, and you're welcome!

We have an operation directive to go with no code solutions when we can.
Your coded answer is amazing and I've captured it for future reference.

Thanks
