thanks for your reply, sorry for my english, I will explain to you more what I want. What I need is a code on a inputbox settings that automatically remove the value that you key in.
I am developing a payment gateway and every guest or user who visited my website anywhere it happens that when they type their credit-card number on mozilla browser the value is automatically saved by the textboxes once you try to use the browser again so I want to remove the save values by means of coding because not all browser users are familiar in Edit>Preference>Privacy command.
