Does it check specifically for Submit.x and Submit.y? or does my goof
script work if I put in the full URL? *heheeh*. I noticed he had that
bug too when I used wget to grab circle.php (the circle center was at
the origin), but wasn't sure if his validation code checked it (this was
after I sent my goof response :)

Cheers,
Rob.

Nope, it does actually check for Submit.x and Submit.y ;)
