How do I acces a var from the main time line in to a movieclip?

I’m making a quiz-type animation, since I’m new with ActionScript I had developed my own way to make this work.

I want to add like a meter that shows one out three position depending on the answer given, I had made this animation as a movieclip but now I need it to react according to the answer, so it changes on every question to do that I need to access the variables I’m using in the main time line, how can I access the the main time line variables from the movie clip?

The movie clip (meter) is basically the background and the questions will change and advance on top of that movie clip so it’ll change with each answer until you get the final result.

My FLA file is too big to upload it to the forum but I can email it to whom want to help me, THANK YOU!!!
