Hi, I have been following 2 courses by Guy Stevens his Complete invoice and two portals onto one invoice. The problem i am having is the everything works fine with the Products portal, having copied this portal and followed the instructions changed the fields etc. I now can input the services but when i click outside on the main invoice area am losing all the information in my service portal. I think it has something to do with InvoiceDetails table, the figures in the main invoice is not updating the figures from the service portal. This is driving me crazy as i can't sort it out and would be really grateful if someone knowing filemaker better than myself could help me out.
