Comparing two columns in two different worksheets

[Guest]

I am trying to compare numbers in two different worksheets. In worksheet one
I have a list of number and in worksheet two I have a list of numbers, but I
want to know if a number appears in both worksheets. How do I do this?
Thanks in advance for your assistance.

With the lists in Sheet1 Column A and Sheet2 Column A, somewhere else
=IF(AND(COUNTIF(Sheet1!A:A,Sheet1!A1)>0,COUNTIF(Sheet2!A:A,Sheet2!A1)>0),"Duplicate","")
and copy dwn to the last cell in the ranges,
Regards,
Alan.

Use a simple countif, assume you do this in sheet1 and the other list is in
sheet2, insert a new column next to the one in sheet1 assume the list is in A
and the new column is B

=IF(COUNTIF('Sheet2'!$A$1:$A$500,A1)>0,"Exists","Non-existant")

copy down the formula

I am just trying to be clear on how to use the formula, so if I have two
separate spreadsheets with numbers and I want to see if the same numbers
appear in both spreadsheets this formula should work? Thanks again for your
assistance.
