Here's some general code, that's probably close:
Dim db As Database
Dim rs As DAO.Recordset
Dim sql As String
Dim strTO as String
Dim strCC as String
sql = "Select * from qryInvAssessmentMemo"
strTo = ""
strCC = ""
Set db = CurrentDb()
Set rs = db.OpenRecordset(sql, dbOpenDynaset)
If Not (rs.BOF And rs.EOF) Then
rs.MoveFirst
Do While Not rs.EOF
strTo = strTo & rs("FieldTO") & ", "
strCC = strCC & rs("FieldCC") & ", "
rs.MoveNext
Loop
End If
rs.Close
'strip off extr coma at end
strTo = Left(strTo,Len(StrTo) - 2)
strCC = Left(strCC,Len(StrCC) - 2)
'Do email
DoCmd.SendObject acReport, "rptMRC_Summary", "SnapshotFormat(*.snp)",
strTO, strCC, "", "", False, ""
Exit_YourSub:
Set rs = Nothing
Set db = Nothing
Exit Sub
