Dlookup not working

[SHIPP]

I am using Access 2003. I have the following lookup in a report.

intFirm = (DLookup("FirmSun", "stblFirmDays", "[StoreID]=" & Me.StoreID &
" AND [OrdGrpID]=" & Me.OrderGrpID))

It keeps on stopping at Me.StoreID saying Data member not found. StoreID is
in the underlying query supporting the report. I also placed the field in the
detail section and made it invisible. It is a numeric field. What am I doing
wrong?

I found the issue. Thanks.
