I have a module that is dimensionalized by row ID (#1-#n), no parent member for that list. It is an input template to model new expenses. What I am aiming to do is to have another line item (could be in a different module if needed) that will look to see if any of the rows have data.
Essentially each row has line items that need to be input. Once all input then that row will be "Ready." I want to summarize so the user knows if the entire sheet is "Ready."
Both answers given are good answers. If I understood your ask correctly, you need to know if the whole "form" has been completed or not, not necessarily the number of completed items. In this case, going with a boolean and using the ANY (or ALL) functions depending on your case, would be the better solution.
