I got an ArcPad project file from our client which includes related tables. The related tables are loaded within the form when a new polygon is added.

Now I want to limit the number of features that can be added for this polygon. I thought of putting a loop on the "add" button, but I don't find a way to access or manipulate it.
Can anyone help me on this?
Besides: I found a spelling mistake in the Alias and the field name, when looking at the list view of the related table. Can I correct those somewhere? I can only access the caption at this point.
