Your code has an error somewhere. This is impossible to troubleshoot without the complete code, since the error can be anywhere (in fact the error stack often tells you it's at the end of your code).
The following trick is a lifesaver, so pay attention: Your code editor is trying to help you. Whatever editor you're using (except notepad++.exe. Don't use notepad++!), clicking on any (and I mean any) special character such as parentheses, square brackets, curly braces, double and single quotes, will automatically highlight the one that matches it. The screenshot below shows this: I clicked on the curly brace at the bottom, it shows me the one on top by highlighting it. Learn this, and how different functions and event handlers "look" like.
