Hi Jagger

Don't know why you're getting zero.

I replicated this and it worked fine for me, although the answer is
actually 5 ( 16, 21, 31, 43, 59)

I'm using Sumprduct to get a count of matching numbers in the
following two sets, going from A1:T1, A2:T2

4 12 14 15 16 20 21 22 28 29 31 36 43 47 49 58 59 60 66 69

5 7 9 13 16 21 27 30 31 37 41 43 45 48 51 52 56 59 64 67

the formula I'm using is =SUMPRODUCT(--(COUNTIF(A1:T1,A2:T2)0))

I keep getting an answer of 0, the answer should be 4 (16, 21, 31, 43
match)

Can anyone see what I'm doing wrong?? Thanks

Yup, answer should be 5

Still can't get the right answer??? I've deleted everything on the
spreadsheet, replaced all the numbers and still get 0???

K, closed Excel, started a new worksheet and everything works fine??
Going for coffee....

Could be that the sheet had it's auto calculation switch off.

Should you come across this in the future, hit F9 and see if it updates.
