I'm stumped on this one.

My portal shows related records for some entries, but not for others.

First layout lists Customers (and some details)

Clicking on a button takes you to the second layout which correctly gives all the details of that customer (same table).

The second layout also has a portal to show the related records from a table listing documents.

It works for some customers, and not others. I've ensured that the indexed field entries are correct (they are even automatically entered !) but they don't show up.

Any ideas, please ?

Check that the relevant keys of the records on both sides of the relationship are populated as expected, with no extra characters. Also make sure that the corresponding keys are of the same type.

Also make sure your portal is connected to the correct table occurance, same for the fields within the portal.

Got it ! Thank you both for your help (indirectly!)

It was a relationship problem. Even though the relationships were quite simple, I had them daisy-chained through another table (A related to B related to C) instead of independant connections (A related to B, A related to C). It just LOOKED that way on the screen. :-P

Thanks again for pointing me there...
