The problem is, I have created a query that obtains its parameters from two combo boxes, ei, this first combo provides a supplier, the second displays that product range for the supplier. my question is? How do I create a query that will display all records if one of the criteria fields is empty. sort of -- IIf(isnull([forms].[Reports].[supplier],"*")) -- Now i hope i dont look to dumb, but I cant find any simple answers anywhere.
Any help would be seriously appreciated.
Kind regards
Dan
 
WHERE SupplierID = [Forms].[Reports].[supplier] OR
[Forms].[Reports].[supplier] IS NULL

BTW, I wouldn't name a form Reports: that's a reserved word, and can lead to
problems.
