If that formula isn't working and it's entered properly then the problem is
data,
highlight each part of the formula (as below) in the formula bar and tap F9,
you may need to shorten the range a bit and you will see if it is evaluating
TRUE or FALSE. If it's false and you think it should be true then you have a
data issue
(Production Calendar!C11:C20="Memco")
(Production Calendar!D11

20="SMM")
Click the red cross after checking each part
If they are evaluating correctly then check your numbers. Are they really
numbers?

could help me figure it out that would be great. i have been using the formula
=AVERAGE(IF((Production Calendar!C11:C105="Memco")*(Production
Calendar!D11

105="SMM"),Production Calendar!G11:G105))
