[Javascript/Php] Neopets Auction Bot Project (3)

The latest update to the auction bot.

*IF YOU WANT TO USE THIS, YOU HAVE TO CONTACT ME*
The reason for it being private, is nothing to do with me being selfish or anything, but the fact that this script queries my MySQL database between 6-10 times a minute, and I dont want it to run too slowly. Ive posted everything required to set it up here, however, if you need help, feel free to contact me (Details: my contact details -> about)

Its almost fully automated now, refreshing, opening, closing pages correctly.
There are only a few things to sort out, but to the average user these problems aren’t noticeable (check the grease monkey var for the script after running it for a while -_-)

Source for the PHP remains the same, so check the other posts.
Below is the greasemonkey script:

Theres also a clue in this post as to how you can easily access my host if you want, its kinda… obvious.

Remember, this isnt the final product. Its still being worked on.
