When I open a particular workbook I get an automatic message which says that
the workbook you are opening contains automatic links to another
workbook...would you like to update this workbook with changes made the
other workbook?

The problem is that I have no idea where the "other workbook" is referenced
in the workbook I am trying to open. I have gone through the workbook cell
by cell but haven't been able to locate where the "automatic link" is. Is
there any way to find it?

Thank you!
