Any recommendations out there?

Many xla plug-ins are not cross-platform. Occasionally you will find one. The Named Range manager (www.decisionmodels.com ) is one that has been modified to work in both environments.

As far as the path, Macs use a different path method for reaching the file. I can provide more later tonight.

Are these Macs OS X? Are they using Excel v. X or Excel 2004?
