i...for the life of me can't get a sumproduct formula to work.

in a seperate worksheet i have column am. i want it to search column am
for
the number 3. after that i want it to go to column x and tell me how many
of
column am's number 3 have a y in column x.

i'm using
=SUMPRODUCT('Orders-Breakout'!AM:AM=3)*('Orders-Breakout'!X:X="Y")

i keep getting a #num! error...what am i doing wrong?
