Thanks.
Honestly, I'm quite embarassed with the source code as it's pretty amateurish. I'm going to have time over the X-Mas break to clean it up a bit.
I've needlessly duplicated some much of the code that as I'm looking at it right now realizing I've wasted so much time to do the simplest things.
I had surgery on Thursday, so I've had a bit of time on my hand and basically have re-written quite a bit of it last night.
There are quite a few bugs left.
Since I'm not a "Professional Programmer" I work on something...and if I think of something, I put everything on hold and start on the new thing. It's a pretty bad habit...
I've created an order form as well. Like everything else, it's only partially done.

The register part works pretty well...(Relative to the state it is at right now.)
I'm pretty tired and there's a small mistake, I just can't figure it out right now. I'll look at it tomorrow to get the order form to work properly.
