    Hello, Praveena,

    Please help us to help you.  We need to see your code, especially whatever function is defined that contains that line number you mentioned in the error message.

    V/r,

    Hi, Praveena,

    It never even occurred to me to point out that a CF error will give the actual line number of _code_ that generated the error; but JavaScript is a client-side script, so it will provide the line number of the HTML that is generated by the server, not the line number of the code that produced it.  My apologies - I should have been more thorough in formulating my request.

    If you could, please, do a "View Source" on the HTML after the JavaScript error alert is dismissed, and provide the JavaScript function or code that is causing the issue.

    V/r,

    ^_^
