I have two repeating rows and would like to add a rule such that the dropdown choice (a list lookup) in each row cannot be similar.
How is this done?
What sort of differences should there be between these dropdowns?
Different set of values?
Do you want then to use these selections in the workflow or just have them visible in the form?
If just visible, then the easiest way is to add (of course) both dropdowns to the repeating section, set their names, and then set formatting rules to them:
And using similar rules you can add more fields and show them only in related rows.
