I have been looking at your examples and have come up with aīest effort. The Criteria to find the particular record.When we use the DLookUp function we need to provide it with three pieces of information (called parameters). So applied to our scenario, we can use a Calculated Control containing the DLookUp function to obtain the item name from tblProducts (based on our knowledge of the product item's ID). It is often used as a function in a Calculated Text Box Control (see previous post for more information about Calculated Controls). The DLookUp function allows the Access Developer to look up the value of a field from a table other than the form's actual Record Source. This is where the DLookUp function comes in handy. That is to say, somebody using the form is not necessarily going to know which product ID relates to which product item name. Obviously, this is going to be a problem from the perspective of user friendliness. Having selected tblOrderDetails as the form's Record Source, we realise this table (part of a Many to Many Relationship) does not include the name of the product item as one of its fields it instead uses the item name Id as a foreign key from tblProducts. In particular I look to Stephen's site first for advanced topics related to forms and reports, especially interacting with the Windows API.Imagine the following scenario: we have created a form to display information contained in an order details table.
