Would someone be so kind as to tell me why I get Err in the Runtot field from this query ? It seems to run fine except no totals.
Code:
SELECT DatePart("yyyy",[Recdate]) AS AYear, DatePart("m",[Recdate]) AS AMonth, DSum("Creditamt","DatePart('m', [Recdate])<=" & [AMonth] & " And DatePart('yyyy', [Recdate])<=" & [AYear] & "") AS RunTot, Format([Recdate],"mmm") AS FDate
FROM TblPayments
GROUP BY DatePart("yyyy",[Recdate]), DatePart("m",[Recdate]), Format([Recdate],"mmm")
ORDER BY DatePart("yyyy",[Recdate]), DatePart("m",[Recdate]), Format([Recdate],"mmm");
