In order to use the Compare and Merge Workbooks feature see Excel Help: "Make
sure the copies of the shared workbook that you want to merge are all stored
in the same folder. To do this, you must give each copy a different name."

Although it's name suggests otherwise, the feature is not used to simply
combine the content of two separate & distinct workbook files. One must start
as a copy (Save As) of a file designated as Shared even if nobody else uses
it.

Hope this is useful |:)
