Thanks for your time Beth.
Have been looking in References and still can't see anything resembling Utility.mda. All I've got checked are:
MS Access 10.0 Object Library
MS Excel 10.0 Object Library
MS Office 10.0 Object Library
for App Extensibility 5.3
I'm only a novice at programming so wouldn't recognise if a reference was called by another name. Could that be the case?
I'll be leaving work soon so if I don't answer to your reply I'm not being ignorant - just home.
Thanks for your patience.
