Add an if statement to the formula i have

I have this formula =IF(AND(A2<>1,A2<>2),C2,80-SUMPRODUCT(($A$2:$A$572<>1)*($A$2:$A$572<>2)*($B$2:$B$572=$B2),$C$2:$C$572)) that works great on my worksheet, the only thing I have tried to add =IF(A2=2,0,"") but can not get it to work. Any suggestions, I love this site you guys save hours of time plus I am learning so much by taking the formula apart and seeing how they work.
