I'm trying to change some codes in a module I created in VBA. And the result
when I use F5 to run the module is ok. But when I try to call it by click a
button, some of the result lines are disappeared. I've tried to debug the
module step-by-step but the result is always the same.

Is there anyone encountered such weird situation? Could you guys tell me why
this could happen?

Thanks a lot!
