Is it possible to create a link to another worksheet or an external workbook
that would work by simply placing your cursor over a cell, thereby displaying
the data as a "pop-up"? If not, how about clicking on the cell and bringing
the information up as a form or window? The second data source is an excel
spreadsheet (or may be up to 1200 separate spreadsheets) and will be large so
I'm thinking it would be more efficient to reference it as a separate data
source rather than internally. I simply want to access the information
quickly and simply without necessarily having to create a macro to open the
source and then split the windows, etc.

Thanks,
