Let me try this again. What you first need to do is create an identical raw material item field on the table of your subform. Now go to your subform in design view and add that field to your form (Don't worry, we will make it invisible so that the users don't have to see it twice). Now right click on the field and select properties. Go to the Event tab and select the field Before Update. Now click ... and select Code Builder. Your code should look something like this:<br>Me![RawItemNo] = [Forms]![frmMain]![RawItemNo]<br>This tells Access to pull the item no from your main field and display it on your subform. We are going to make it invisible, but what it will do is link the item number from your main form to the description on your subform. Now right click the field again and select properties. Change the Invisible field and the Tab Stop field to NO. Finally, go to your main form in design view, and right click - select properties - on your subform. Go to Link Master Field and Link Child Field - fill in the RawItemNo field in here. Now when you enter an item number in your main form, <br>Access will duplicate it to the invisible field in your subform, and pull up the related description. Hope this helps!!
