Re: [MS_AccessPros] Count of count

Robin-

Not sure why you included HAVING Count(Data.fFirstName) Is Not Null.

Your query should work without that as long as Females have a Null value in mFirstName (Count won't count Null) and vice-versa. Try this:

SELECT Count(Data.fFirstName) AS CountOffFirstName,
Count(Data.mFirstName) AS CountOfmFirstName,

Count(Data.fFirstName) + Count(Data.mFirstName) As TotalRes
FROM Data

Thanks Duanne,

Females are in the field "fFirstName" and males are in the field "mFirstName". All are residents.

So I would count total residents as the sum of the two fields above.

Do you need any more information.

Cheers,

Robin

Robin,

I don't see anything in your SQL that identifies gender or residents. Do you have a field for Gender? If so, what are the possible values?

Can you provide some information about your table and how you would count "total residents"?
