I have a spreadsheet with the following columns:
* Col. A: Part numbers
* Cols. B, C, and D: Current data that pertains to part numbers in col.
A
* Cols. E, F, and G: Proposed new data that pertains to said part
numbers. Such data is obtained by formulas linked to other
spreadsheets.

What I would like to do is have a formula in col. H that inserts an "X"
if any data in cols. B-D is different than that in cols. E-G. If none
of the data is different, then it should insert a blank ("").

Thanks for your help.
