Total of input fields within a repeat

I’m trying to capture the total of a multitude of input’s that are generated in a repeat children. I can easily get the INITIAL total of these inputs by using the data returned by server connect, however I need the real-time total as the user changes the inputs.

For example, in the screenshot below, the user can change 20.00 to 30.00, so I need access to the sum of 30 + 4 + 1:

Here is the repeat children:

How can I calculate the total of all the “distro_amount” fields contained within the Table Body repeat-children and store in a variable or another input?

Thanks for the help!
