dkyadav80, learn to use code tags properly. I'll show you how:
&#91;CODE=javas cript]var test = "test";[/CODE]

Replace "javascript " with something else for other languages. You can even omit the language, but at the very least use the code tags properly.

I've merged this thread with one you asked earlier since it relates to the same problem.
