>I am quite new to this, could you perhaps go into a bit more detail on how I can acomplish this.

Basically, one approach could be this:

In the FORM tag, add onSubmit="RedirectUrl()". Then, you can write a javascript function RedirectUrl to store the URL in the document.location property. That can go like this:

function RedirectUrl()
{
   document.location="http://www.levelextreme.com"
}
