I tried doing the pages over again. There was a problem, that one of the tbls was wrong.
After that the pages came out fine except for the detail page, where I had to correct the recordset again by hand.
The only thin that is still bothersome, is that I cannot include search on the result page. If I place the check mark for that, the process stops with a java script error. Tried a few times both ways, always, when the include box is checked the process stops with the result page.
