Dan,
This is how I have it set up.
Logo 1 and Logo 2 are (Text) Pick Lists
Central Region and North Region are set up as children.
I have assigned Central Region as the child of Logo 2 and North Region is the child of Logo 1.
If I look at the form it contains 2 Pick Lists Logo 1 and Logo 2. In the drop down list for Logo 1 it lists all the Central Region Logo's. In the drop down list for Logo 2 it lists all the Logo's for North Region.
All that works great my question is, How do I switch from Logo 1's pick list to Logo 2's pick list and have the Logo's pertaining to each list show up in preview? It either picks one or the other lists. Is there are way to access both lists?
