Restrict data entry to a repeating group

Hi. There is a repeating group (1), which forms a numbered list. From the repeating group (1), the data goes to another repeating group (2), i.e. they are duplicated. The repeating group (2) is located in a fixed group and its boundaries are not changeable. How can I limit data entry within fixed boundaries in a repeating group (2)?
I hope I made myself clear).

Would you mind sharing a screenshot of the way your Repeating Groups are setup? :blush:


I would also add that the added data can have from one to four lines and the total height of the list can vary significantly.

Use action :filtered

It’s not quite clear how this can help. Can you elaborate on that?

Really? No one knows?
