Shot in the dark:
When you set your second value list, presumably you're selecting "show only related records starting from..."
Make sure you're starting from the portal table occurrence, not the layout table occurrence.
If this isn't the issue, could you put up a screenshot of the value list definition? Maybe even a screenshot of the portal on the layout?
I modified my tables to consolidate "positions" with "members". The portal is based on ProjTeam. Relationships are as follows:
The "position" dropdown selection works. The conditional value list for "members" works as long as the selection has previously been input. I would like to have the "members" as popup with allowing entry of other value. This, I cannot get to work.
Thank you in advance.
