Many thanks for the replies. I understand now about the "_x" and "_y" suffix.
Aparajita and Brad correctly identified the "no form variables" problem. I had copied faithfully the demo "backend" page code (which did work) into my real db web folder. What I had missed was the fact that I had inserted a new "Front End" page (with links to various pages) immediately before the "backend" pages. When adding the page links to this new page, created using DreamWeaver, I omitted to add the "/4DCGI/" to the links. DOH! I will always insert "/4DCGI/" in a link. I will always insert "/4DCGI/" in a link. I will always insert "/4DCGI/" in a link. ... ;-) Now, if only I could find a way to select A4D commands from inside DreamWeaver, it would save a bit of messing about (going back and forth to BBEdit). Never mind... Once again, thanks. Cheers, KG
