If there are no entries in the subform - to hide the subform

[kev1n]

The function works for me. E.g. when calling this function in the "Access Levels" form, all subforms are hidden.

Found a mistake in the problem description.
On the main form, I need to hide the run objects (type = iFrame)

First the main form is created and then the run objects. So at the moment, when the main form is loaded, the run objects are not yet fully loaded.
Therefore, you can't retrieve the number of rows of a run object from the main form (while the run objects don't exist yet)
