I don't quite know what this means. "changes the inventory record"? What record?
If you have a CommandButton that opens the report, post the code here so we can see it, using the "#" code tags button. Start with Private and go to End Sub. What is the SQL for the RowSource of the ComboBox and which column is bound?I do have a combo box on my form where the user selects a BOL and it finds and changes the inventory record based on the BOL that is selected.
