Help with html / php contact form

Question

Hi guys I was hoping to get some help with a contact form on my website, to be honest I havent a clue about php but kind of okay with html thats why the php code is just a copy and paste from some website, just trying to marry it up with the html but getting errors.
Hopfully one of you can see the problem.
Error on Submitting:
Notice: Undefined variable: name in \\nas44ent\Domains\g\gethinhayman.co.uk\user\htdocs\send_form_email.php on line 69
Notice: Undefined variable: message in \\nas44ent\Domains\g\gethinhayman.co.uk\user\htdocs\send_form_email.php on line 75
We are very sorry, but there were error(s) found with the form you submitted. These errors appear below.
The Name you entered does not appear to be valid.
The Comments you entered do not appear to be valid.
