I'm not sure what I am doing wrong, but here is my SQL Code within my Access Query:

SELECT Count(qryVendorX.[Item #]) AS [TotalItems]
FROM tblItemMaster RIGHT JOIN qryVendorX ON tblItemMaster.[Item #] = qryVendorX.[Item #]
GROUP BY qryVendorX.VendorNumber, qryVendorX.VendorName
HAVING (((qryVendorX.VendorNumber) = [forms]![frmPOTransHeader].[Vendor #]))

IIF (qryVendorX.[TotalItems])>0
SELECT qryVendorX.VendorNumber, qryVendorX.VendorName, qryVendorX.[Item #], tblItemMaster.Description, qryVendorX.[Vendor Item #]
FROM tblItemMaster RIGHT JOIN qryVendorX ON tblItemMaster.[Item #] = qryVendorX.[Item #]
GROUP BY qryVendorX.VendorNumber, qryVendorX.VendorName, qryVendorX.[Item #], tblItemMaster.Description, qryVendorX.[Vendor Item #]
HAVING (((qryVendorX.VendorNumber)=[forms]![frmPOTransHeader].[Vendor #]))

ELSE
SELECT tblItemMaster.[Item #], [Department] & "-" & [Account] & "-" & [Sub-Account] AS [G/L Account], tblItemMaster.Description
FROM tblItemMaster
ORDER BY tblItemMaster.Description;

My goal is to display a list of items specific to vendors if the information is in the Vendor Cross Reference Table.  If the Vendor is not in the cross reference table, just display all Items.  Any help is greatly appreciated.

You would have to use this syntax in MS Access:

IIF(condition, true-statement, false-statement)

If you are trying to display a full different query based on some condition, you may be better off moving to VBA code and then it is of syntax:

IF condition THEN
    'true-statement
ELSE
    'false-statement
END IF

Thank you for the comment.  I didn't even think to go that way.  I am trying to populate a lookup based on the condition being met with one query and if not a different query.  I was thinking that I had to make the query do the work rather than the event on the lookup.  Thanks again.
