Count Distinct Response

Someone (Kevin i think) was looking for a way to do a distinct count,
not sure if i'm using this groups thing right - was trying to supply
answer. Anyway, this is a function i wrote for it... hope it gets to
you. just copy and past it into a module and call it as you would
dcount()

Public Function CountDistinct(Field As String, QueryOrTableName As
String, AdditionalCriteria As String)

Dim dbs As Database
Dim rst As Recordset

Set dbs = CurrentDb

If Not AdditionalCriteria = "" Then
Set rst = dbs.OpenRecordset("select distinct " & Field & "
from " & QueryOrTableName & " Where " & AdditionalCriteria)
Else
Set rst = dbs.OpenRecordset("select distinct " & Field & "
from " & QueryOrTableName)
End If

CountDistinct = rst.recordcount
rst.Close
dbs.Close

End Function
