1. Are you sure upp is being set? Maybe its not finding that.
2. Your findcontrol for label3 will work, if in fact, label3 is there. Are you sure you have a label3? Is label3 inside anything else?

if it's on the masterpage at design time, try adding the @mastertype directive to the child page and you will be able to access it without the findcontrol.
