    You need to wrap your code in code tags to preserve its formatting. Press the Go Advanced button, select the code and press the #icon.

    Have you checked that all }s are correctly paired with a }?
    Many IDEs and editors have a feature that will do that. Put the cursor on the { press a key combination (CTRL+] in my editor) and the cursor moves to the paired }

    Another aid for solving this problem is to label all the } with a comment about what scope they are ending.

    Where this function ends???? Probably, } is missing here.
