I'm sure I'm missing something basic. I have this exact set-up in one file that is working perfectly but, for some reason, am having problems in another.

I have a field in a portal row which is defined as a button (basically go to related for further detail). For some reason, the button won't click. I thought it had to be something with the layout layers but even when I have brought the field in question to the front, I still can't click. If I take the field/button out of the portal, it works fine (other than the fact that it's not in the portal so I can only ever access the first record, of course).

What am I missing?

I solved this. I'm using a menu file, which is solely globals for navigation control. This file had zero records, which was causing the problem. I created a dummy record and all is well!
