Web-to-Lead form troubles! Help!

For some reason this doesn't work. I have tried it out several times, on the page it belongs on, and then once i created a page with nothing but this form on it. I enter the information, it takes me to the page I entered for it to take me to after the lead is submitted, but the lead never appears in my CRM and the automatic email never shows up. Has anyone else had this problem?
