IF statement not working on formula "0"

[DirtyHippy]

=IFS(A2="Product","Y", A2="sku","",AND(AE2="0",A2="rule"),"N",AND(NOT(AE2="0"),A2="rule"),"Y")

Currently AE2 is a field with formulas that compute to 0, right now it is not recognizing this and calculating to yes for all values.

If AE2 contains numeric zero, then the test should be AE2=0 without quotes around the zero.

And instead of NOT(AE2=0), simply write AE2<>0.

I've also tried the permutation =IFS(A2="Product","Y", A2="sku","",NOT(AND(AE2="0",A2="rule")),"Y",AND(AE2="0",A2="rule"),"N")

That formula returns #N/A if A2 can be anything other then "Product", "sku" or "rule".  For example, can A2 appear blank (empty or the null string)?

It is prudent to always have a TRUE part at the end.  For example:

=IFS(A2="Product", "Y", A2="sku", "", A2="rule", IF(AE2=0,"N", "Y"), TRUE, "")

Aside....  A2="sku","" is superfluous if it is the same as the TRUE result, like mine.

Alternatively, if A2 can be only "Product", "sku" or "rule":

=IFS(A2="Product", "Y", A2="sku", "", TRUE, IF(AE2=0,"N","Y"))

and =IFS(A32="Product","Y", A32="sku","",AND(AE32="0",A32="rule"),"N",NOT(AND(AE32="0",A32="rule")),"Y")
