We would encourage you to try and solve any academic problems assigned with minimal help.

There aren't any javascript errors in the code you provided. There are some issues with it (listed below) but nothing that would prevent your code from running.

What is the code doing that it shouldn't be doing? (Or what isn't it doing that it should be doing)

Issue 1
Your code is lacking formatting. Try indenting your code as it will make debugging it a lot easier.

Issue 2
You're missing a valid Doctype at the beginning of your code.

Issue 3
The html comments around your javascript (to provide noscript support?) aren't necessary in any browser today.
