Hi, I am looking to add a rule on a repeatable to ensure a user enters at least 3 repeatable rows and a maximum of 5. I have figured out how to ensure user does not enter more then five rows. This was accomplished by a formatting business rule. If count(.)=5 then "Don't allow user to insert or delete this control". I still can not figure out how to validate at least 3 repeatable rows are not blank.

If you have a Submit button, you could disable it (or Hide it) if count(.) <3. Would that be enough?

We want to ensure user enters a least a min. of 3 and maximum of 5 Key Activities (repeatable table). I figured out the max. of 5 rule but can not figure of how to validate if user entered at least 3 rows.

What did you think of my advice above?

A screen tip would be preferred. Are there other alternatives?

 You can just define 3 defaults.

Thank you so much! Is there any way to make the first three required and the last two optional?
