Answer 1

If you are the writer of such huge code you should know how to debug it. well I will assume that you are the one that wrote the code, and this is the error here..
-------------------------------------------------------
JavaScript Console
SyntaxError: missing } after property list
Line: 197
-------------------------------------------------------
So check from your above code where one of your closing braces is missing
