Problem getting subfile to display

[UPI]

I'm having trouble getting a subfile to display and could use some help.
This isn't my first subfile. In fact, the panel displayed has another subfile included, which works fine. The display panels are the result of using the Convert DDS program of PUI. I've put this thing through debug and know that the subfile is being populated properly, the SFLDSP and SFLDSPCTL indicators are set properly and it should be working, but it's not. It is, however, my first attempt at using a multi-line subfile.
Is there anything I should be looking for to help me ensure it will display properly? (I can send screen shots and source code but this is proprietary software and I'm not sure who can see attachments)

send a copy of your display file DDS to support@profoundlogic.com. If you identify the record format of the subfile you are having problems with, we can write a test program to write some test data to the subfile.
