Question : VBA functions Trim, Left and Right not working

I'm developing code offsite, on a stand alone machine.  The users have recently upgraded their machines so my code would run at their offices.  We all have Office Professional XP, and I downloaded the libraries for them so we'd all have the same references, namely
Visual Basic for Applications
MS Access 10.0 Object Library
OLE Automation
MS ActiveX DO Object 2.7  Library
MS ADO Extension 2.7 for DDL and Security

My code fails on the Left and Right functions.  I don't have the precise messages at  hand, and since I'm not on site I can't get them at the moment, but I think they had to do with function not being found or something about libraries.  The best thing I can think to try is to prefix them with "VBA.", but I'm wondering if there's not some patch on my machine that isn't on theirs.  Any ideas?  I don't use Trim in the Access part of the application, but it fails in Excel, but Left works fine in Excel.  

Answer : VBA functions Trim, Left and Right not working

are there any other Broken References?  The problem can be cuased by ANY missing Reference, not just the VBA libraries that you specifically downloaded.
