=IF(COUNTIF(sheet2!$B$2:$B$576,B2),VLOOKUP(B2,she et2!$A$2:$K$511,1,0),0)

Your row ranges aren't the same size, 576 versus 511 ?

Try this...

=IF(COUNTIF(Sheet2!B$2:B$511,B2),INDEX(Sheet2!A$2: A$511,MATCH(B2,Sheet2!B$2:B$511,0)),0)

Hello Everyone

I have two worksheets if the number in sheet 1 cell B2 is in column B of
sheet 2 (say B36) I want the number in A36 to be copied to sheet one.

I have written the following but keep getting #N/A - What am I doing wrong
please?

=IF(COUNTIF(sheet 2!$B$2:$B$576,B2),VLOOKUP(B2,sheet 2!$A$2:$K$511,1,0),0)
