Unless, and this s a big unless, your PHP installation is set to have register globals on then you should be addressing your form variables $_GET['nameofvariable'];

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

1. You have a leading "'" in front of the first two $_GETs. That's your syntax error.
2. One of your $_GET variable names doesn't match your form.
3. $premium is not being passed via $_GET.

I said Form variables not all your variables. As in just the ones coming from your form. In addition to the errors pointed out by lgarner.

Well, you still have quotes around your equation. And you're still trying to read an HTTP GET variable called 'premium', which I don't see defined anywhere.

In addition to all this, you were very lucky that your browser tolerated you. There is no INT type for the input element. A stricter browser might get confused as to what you want and not submit the values at all.

The type you would want is text, as in:
Code: 
<input type="text" name="days" />

However, as a first step, I would suggest reading up on a couple php and html tutorials. You demonstrate a lack of understanding of the whole subject.
