now works ok. thanks
Actually, the last screen shot shows that you have no layouts for the Projects table occurrence. It says nothing about how many Project records you may or may not have.
None of what I see of your layout would have any affect on the project details table as your layout is based on Customer_Details and the portal refers to Projects.
Seems like you need a portal to Project_Details if you want to create/edit those records.
Yes - thats correct I needed the portal on Project_Details. Thanks Kaps
