Hi All!

I've got a pageframe with 3 pages on it. Page 1 contains info from my parent table "SYSTEM", Pages 2 & 3 contain info from my child table "FEATURES".

My Data Environment for this form contains these two tables with a relationship line joining the two based on systemid. I originally created the relationship with the "OneToMany" property set to True since there are occasions when there are several child records that relate to one parent record.

All seems to work fine, except that when the user is on Page 1 and is using the navigations buttons to advance to the next/previous SYSTEM record it requires 2 clicks to go from SYSTEM record 2 to SYSTEM record 3. I've figured out that this is because there are 2 child records (in FEATURES) for parent record #2 so it's cycling through both to get to parent record #3. I know this, but I envision confusion for my users.

If I turn off OneToMany in my relationship, there's no extra "Next" needed to go from 2 to 3, but then I miss the 2nd child record for parent record 2 on my Pages 2 and 3.

Any ideas on how to handle this???

MTIA!!!
Mandy
