Need help with a simple web form

I need help with a short form on my website that I "borrowed" from someone. I have the form in the proper format but this is what I need help with:

After all information is entered and ready for submission, I need the info to be sent to an email address.

I would say it's very simple but I'm not exactly sure how to do it.

PM me if you can help and I'll send the form information to you to look at.

Sorry, am on the train... Google the php mail function. You just need a to address, body and subject. In your body variable you would add your form variables, such as name, email etc (or whatever is on your form) using a mix of HTML and php for formatting. If no one else replies send over the form and I'll do it for ya later

Someone has helped me out with this already so thanks to all who responded.
