lap display and respawn handling

i m following a tutorial “time attack racer” to learn more about blueprints. in the 7th video “lap display and respawn handling” the objective is to display the no of laps using debug code and to respawn the car if it flips. issues i faced while doing this:

  1. the lap number doesn’t show up at the top left corner
  2. when i flip my vehicle, it still moves a little bit(yes, even when it is flipped). maybe that’s why my vehicle doesn’t respawn.
    i m currently using unreal engine 4.10.4
    is there some issue with the vehicle blueprint?? help
