Performing DLookUp in a query field?

[MLH]

I have a query that looks up records in tblReturnReceipts
and other related tables. One of the other tables is
tblCorrespondence. The resulting dynaset consists of five
records. Each has a unique [RtnRcptID] field value and
each has a unique [CorrespID] field value.

I would like to add an additional field to the query that
performs a DLookup for some other stuff - using the query's
[CorrespID] value in the DLookup's criteria section. Of course,
I'm having difficulty because I'm unable to reference the query's
[CorrespID] field value inside the DLookup's criteria section.

Anybody have a useful strategy for such a need?

'correspID is a number
expr1: Dlookup("fieldname","Lookuptable","correspID = "
& [tblCorrespondence].[correspID & ")"

'correspID is a string
expr1: Dlookup("fieldname","Lookuptable","correspID = """
& [tblCorrespondence].[correspID & """)" 'correspID is a string

Pick the one for your situation
