I have 2 tables, (1) group table and (2) member table. There is a one to
many relationship: each group has several members in member tables but no
member belongs to more than one group. The linking relationship is a group
ID.

I have created a function that uses this group ID to find all the records in
the members table with the same group ID and create a string of data from
each record and then concatenating a field value. This function works in the
VBA intermediate window when I manually type in an ID:

Function(ID as variant) as variant
code
End Function

Now I want to call this function in a report. How do I proceed?
 
There's a couple of ways of doing this:

First, you could base your report on a query, and include the function as a
calculated field in the query (that's the way I'd do it; it lets me know
I've got the records correct before I get into the report design).

Alternatively, you can add an unbound textbox to the appropriate section of
your report (most likely the Detail section), and set its Control Source to
the expression:
=Function([ID])
You'll need to include the [ID] field as a bound control from the report's
Record Source, but you can set its visibility to No if you don't want it to
show.

HTH,

How does one make a query using a function as a calculated field?

What is the SQL statement?

Something like: "SELECT [name] FROM tblName WHERE [ID] = function(ID)???

Ed

Does this produce one name per line in the view?
