This is the right place for Ren'Py help. Please ask one question per thread, use a descriptive subject like 'NotFound error in option.rpy' , and include all the relevant information - especially any relevant code and traceback messages. Use the code tag to format scripts.
2. And also, if the player lets the timer run out I want the player to be redirected back to the menu they were on after they finish the "You've run out of time" label with the timer now gone. How do I program this?
To have the player redirected anywhere you use flow controls like jumps and labels. You should read the renpy quickstart guide or watch elaine's tutorials on renpy, they're both quite good.
Also, consider googling. I know it sounds silly, but just try <problem name> and <renpy>, you'd probably find a link to a similar question like yours.
