Problem with user registration?

Hi there,
I’m new to all this coding, but I can understand a bit of what it all means.
Anyways!
When ever I try to register a new user I keep getting this error –

Warning: mysql_result(): Unable to jump to row 2 on MySQL result index 15 in /home/fhlinux183/m/mrfree.co.uk/user/htdocs/register.php on line 77

The url is [url]www.mrfree.co.uk/register.php-[/url] so you can see for yourself.

Oh yeah here is the register .php code

[code=php]<?
