In the interactivechange event add code that seeks to the record that is shown in displayvalue.

Don't try to rely on a record pointer for the combobox. Populate the combobox with a SQL statement in the init of the combobox with the primary key as a hidden column. Then on interctivechange, get the key value from the combobox and seek() to the record with that key. If found() do the math and populate your textbox.
