You have a syntax error in your file that is making it unrunnable.

As the very first character is flagged the first thing I would look for is the possibility that you have too many end statements. But if you hover your cursor on the red underline on the first line it will tell you what it thinks is wrong

Please attach the file for us to check. In this particular situation, please do not copy the file in as text in a comment, please attach it, as there might happen to be characters in the file that are not compatible with use as a comment here.
