[Solved] Slight CSS problem. Related to FORM. Please help :)

I'll keep this plain and simple.

I've been having a huge problem trying to place the SUBMIT button beside the URL Form.
Yeah, am coding a new proxy template, but, since I am just learning CSS (been a few days) I've come across a problem.
I tried to look at other CSS files, but I guess am just too dumb to notice what's wrong. Help would be appreciated.

Here's the info needed
URL: http://www.rule-breakers.info/test
CSS: http://www.rule-breakers.info/test/style.css
Both of them have been validated.

Here's the code from index.html

And here's the code from the CSS
