xss

Hi!

I've been reading about XSS and I made a simple form with a text and submit input, but when I execute <script>alert();</script> on it, nothing happens, the server gets that string and that's all.

What do I have to do for make it vulnerable?? (then I'll learn what shouldn't do hehe)

Cheers.
