NoNONV?: IIf([RtgGrp]"NA" or "Non","Yes","No")


Two things, you must use both operands in each comparison
and since the RtgGrp field can not be equal to both NA and
NON, the Or will always be true. Do it this way:

NoNONV?: IIf(RtgGrp"NA" AND RtgGrp"Non","Yes","No")

It is a poor practice to use a name with a non alphanumeric
character, so I strongly suggest that you get rid of the ?
in the calculated field's name.
