Microsoft Access 2010 query gives error: Undefined function 'DCONCAT' in expression

Hi Experts,

I'm trying to move some code from a sample database defined in this question:

to my production database.

The DConcat function is from Patrick Mattews article Domain Aggregate for Concatenating Values.

I have put a copy of DConcat is a module called DConcat.

This is the query that gives the error:
SELECT [MailChimp Export0].ClientID, '"' & DCONCAT("[ItemCategory]","[MailChimp Export0]","ClientID = '" & [ClientID] & "'",",") & '"' AS ItemCat
FROM [MailChimp Export0]
GROUP BY [MailChimp Export0].ClientID, '"' & DCONCAT("[ItemCategory]","[MailChimp Export0]","ClientID = '" & [ClientID] & "'",",") & '"';

This is the query that it refers to (MailChimp Export0):

SELECT CLIENTS3.ClientID, Items.ItemCategory
FROM CLIENTS3 LEFT JOIN ([Item Transactions] LEFT JOIN Items ON [Item Transactions].ItemID = Items.ItemID) ON CLIENTS3.ClientID = [Item Transactions].CustomerID
GROUP BY CLIENTS3.ClientID, Items.ItemCategory;

Regards,
Leigh

3. Implementing DConcat in Your Access Projects

To implement DConcat in your Access project, all you need to do is add the source code above to a "regular" VBA module (i.e., not a class module, nor a code module for a Form or Report).  Once you have done this, you will be free to use the function in your queries, forms, or reports in the Access UI, or you may call DConcat from your other procedures in the VBA project.
