I have tried everything to fix this, can anyone help?
It looks like this was addressed in your other thread! Malformed If Statement (Expression #1) - Alteryx Community
Rewrite the condition like IF ( ([A]="ABC") OR ([A]="DEF") OR ( [A]="GHI") ) Then "Answer" Else "NA" Endif
With one single contains multiple entries check will not work or else pls write multiple contains with OR condition like above.
