Pl Check any Error in Javascript Program

As a full member now, you should know that we expect your code to be posted in [CODE] tags (See How to Ask a Question).

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use the tags in future.

Nice try with the code tags. Unfortunately, you used <code> instead of [code]. The code tags are enclosed using square brackets.

What errors do you see? Check the error console.

As I said, this is old code. If you've not written this, I would suggest finding a newer version that works in modern browsers.
