Hi.
I am a newcomer and I need your help.
I need a formula that can compare a column of numbers (Column A) "LabMaster"
with a 2nd column of numbers (Column C) "ScanFiles" and copy each matched
number to Column B, adjacent to its match in Column A "Labmaster.
(Possibly 4,000 numbers in "Labmaster".

Thanks
Clive
