Hello. Thank you all in advance for your help.

The task I am trying to do is to perform a "where used" check. By "where
used", I mean that I want my workbook to do a check of every worksheet in the
workbook and report (put the sheet name(s) in a cell) any worksheet where a
specific cell is used.
In other words:
In a worksheet called "data", I have a set of values in column A. The
values from worksheet "data" are used to varying degree, by hyperlink, in
other sheets(worksheets X1,X2,X3, etc). The value in sheet data, cell A1
might only be used in X1, but cell A2 might be used in sheet X2, X3, X10)
As I mentioned, what i want is for a way to automatically output in one cell
which sheets cell A1 is used, and in another cell output where cell A2 is
used, etc.
