Vlad, no I don't decompile forum db's as a rule and I didn't decompile this one although I often compile them out of curiosity. AFAIK, the code project you see can get out of sync with what is really compiled. If that means it continues to work with a missing variable but won't on another pc, there must be a hidden file or something that is missing on the new pc, whichforces a full compile when you try to run it. Just speculation on my part.
If I want to decompile:
Windows Start menu > right click > select Run & enter msaccess /decompile in run dialog
Access starts, hold shift, choose file
Close Access & reopen file and compile
The more we hear silence, the more we begin to think about our value in this universe.
