>Are you using your own copy of the classes dbf? This will cause a problem if you have a copy in your application directory and the program is also calling the framework copy.

No, I went pretty much by the example in the book. The classes dbf is in the \mmortals\common30\libs directory and the new lookup table that I created is in the \app\data directory.

I've been looking at some of the other posts about the resource file at the suggestion of Victor Campos, but nothing yet. I've moved my foxuser files around and tried turning RESOURCE OFF, but still get the error.

Thanks to both of you, I'll keep trying!
