I cannot get this formula to work:
In E2 Sheet2 I have:
=IF(COUNTIF($A$2:$B$721,Sheet1!A2:B721)+COUNTIF($E$1:E1,Sheet1!A2:B721)=0,"Entered","")

On Sheet2 I'd like to check for data from Sheet1 and place "entered" in
column E.
This formula gives me "entered" all the way down. Sheet2 has data in it that
is exact from Sheet1 plus new data.

Can someone please advise?

TIA
