Hi. I posted this message on November 6th
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".

And Jacb Skaria relpied : In cell B2 =IF(COUNTIF(C:C,A2),A2,"")

If this post helps click Yes. Yes it did work. Fantastic!
However, I need to tidy up the spreadsheet.

Is it possible to add to this formula?
At the moment, when executed, it leaves empty unmatched cells in column B -
a large number of them.
Can the formula be extended to: if cell in column B is empty, delete row?

Thanks again
Clive
