=LET(
a,(A2/A1>-200%)*(A2/A1<200%)*(A2/A1),
IF(a=0,"NM",a))
Looking at the conditions you explained, it's impossible for it to perform the actual calculation unless it was exactly 200%.Thank you for the responses but neither formula is providing a solution to all 3 results.
I am guessing that you misspoke, and for the part in red you meant to say "<-200%".Hello - I'm trying to build a formula where , IF result is >200%, return "NM", IF results is <200%, return "NM" but if result is between those parameters then calculate the result.
=LET(p,A2/A1,IF(ABS(p)>200%,"NM",p))
=LET(r,A2/$A$1,IF(OR(r>2,r<-2),"NM",r))
