It appears I've run  into a small road block. Using the A + 1,
I can find  the row, find the column and the date  goes in perfect.
Like a dream. But now I have hopefully a simple problem  to fix..

Each PO number  could be entered  in multiple times (all in column A)
based on the number of scanners being sent in for repair.

This will find the first reference for the PO and change the date
the way that it should, but as I said if this PO is on the sheet
more than once, it will not find/change any of those.

Is it possible to have it look for any more references of that PO
number and change those as well?
