>>>Thanks Edward! That works perfectly, but I found I also need a count of records that don't match either criteria. So I tried: IIF(ALLTRIM(famsingl)"F" OR ALLTRIM(famsingl)"S",1,0) AS fblank but this is always returning 1, and I tried IIF(ALLTRIM(famsingl)"F",IIF(ALLTRIM(famsingl)"S",1,0),0) AS fblank but this always returns 0.

I don't know. It should work OK without ISBLANK(), but if it works with ISBLANK() so use it (take phylosophical approach).
