Program Skipping

I have been working on a code for ringmaster and it worked just fine yesterday but today, when I press run it shows a green line going over some of the code skipping lines. My robot does not move. Any tips? (I have restarted my computer, robot, changed the battery, written new code, and reconnected motors)

Did you change any curly bracket? Check these. They can cause trouble like this. Hope you have solved it by now.
