In my previous question, I forgot to ask about using the "Find" form functionality in my containers. I already created a container that has a "Find" button. In it's Click method, I do a:

THISFORM.cFindForm = 'CustomerFindForm'
THISFORM.FindFormActivate()

This works OK, but I get an error when I select a one of the returned records in the find form. (NGOTOPAGEONCANCEL is not found). Before I spend a lot of time trying to find out where I did something wrong, I'm wondering if this will even work (ie. Find in a container instead of directly on the main form).
