Hiding a field or table


I'm new to Ninox.  I have some individual fields and some sub tables that display my old imported data.  I want these visible until the user fills out info in the newly created sub table, then the old table is to be hidden.

I thought the formula might be- display field only if there is an entry in the new table greater than 1?

But I don't know how to write this formula correctly.  I've managed to hide other fields, but not when working with info in sub tables.

You are absolutly right. In the option "Display field only if" you give this formula:
cnt('NewSubTable') >0
