Subskid Keyarn It will be beta to use pc cuz of its large textbox content
U can try with ur phone, But opera mini fp mod is preferable
Then click on the file, wen it opens, scroll down to open in code editor and click on it then do your editings and save
Note:the code editor will be hanging cuz of the use of mobile phone and is only ment for wapmasters expert because wrong inputs or deletes of code will render the page useless!
But i will advice you to request any code you need from the page here!
