Thanks to Helen and Claudio for the replies

This morning, before I had downloaded any mails, I deleted the Query,
dropped a new one, the entered the statements
again, and every thing worked fine. So for some reason, there was some
errors hidden i the old one.

And Claudio, don't expect a newcomer to know everything at once.
The deleteSQL was a copy error in the mail, and the statements was based
on the Getting Started Guide, from
Jason.

And if I have missed something, I'm still learning Interbase and IB Objects.

Regards
Freddy
