As already noted, you need to review/understand the event sequence. When you do "set focus", SOMETHING already has the FOCUS. You need to "get out" of 'there' before you can go anywhere else. Hence "LOST_FOCUS" from SOMEWHERE. In this case, is is/was (obviously?) PartNo?
Dont feel to bad. WHOLE books (and NOT small ones) have been devoted to the event driven process.
