}

I have the same assigment but the files given I already have.
I have been trying to get it to work together for some time now, I have been trying to make a new variable in the frame file but with no luck, should the timer variable look similar the the button ones?
Just not moving forward now so figured it wouldn't hurt to ask the quesiton.

Any guidance is greatly appreciated.
