Frustrating '@' sign

After going to work and coming home I loged into the site and thought I had lost all my login work I had done last night and this morning however one link was pointing to a different version of the file which means that most of my trial and error this morning and frustration probally could have been avoided.

On the bright side, one change (that I think I had tried this morning without success) was all I needed to get a part of the register.php working. I was working on checking to see if the user had already signed up and hence avoiding duplicate users. It seems at this point that all I had wrong was an '@' that shouldent have been there. something that I had noticed this morning. Guess it took a fresh pair of eyes and a break from it to notice it. I am glad its working now, and either tonight or tomorrow sometime I will be making the INSERT statements so that the registration page will be working completely (so to speak, obviously tweaking the code and cleaning it up will be in order).
