Have you tried if it works when using the complete path, something like this<br>tbl_report!C:\DATABASES\data.mdb<br><br>PS. Thanks for your answer to my other question, I allready found the problem. I added the path of the user defined functions file in de WindowsNT environment settings and I didn't restarted the PC. It seems to me that NT only accepts new path settings after rebooting.<br>
