Beside the player’s selection choice, we also want to provide the player’s reaction time to the instructor.

My task was to display a timer during the game (in second). Every time  choose a selection, then the timer will restart at 0 and counting up.

I was able to display a message Time: and the amount of time increasing within second. 

I was not success on restart the new timer after player select an answer. It seems like it does restart to 0, but two timers is running on top of each other. I am still working on it and will update on the process.
