Okay Im guessing this is PHP .... basically if you go on www.cbfsms.com there are 2 textboxes a number box and a message box. I was wondering how do i find the names of these boxes and edit them in the url for example

http://www.cbfsms.com?number=4407123...ssage=helloooo

so when u enter that url into the adress bar the conent in the number box in 4407123456789 and in the message box it says helloooo

any help? If this is possible and if anyone is kind enough could you find the names for me?
