joecooper Posted September 4, 2011 Share Posted September 4, 2011 Hi, Im trying to add a form where the user can enter how many clicks they wish to purchase for advertising, but with discounts for over 500 clicks. I need them to enter the amount, and instantly would appear the total price (0.01 per click). but 50% discount for over 500.. Im pretty much trying to do what this site has at the bottom of the page: http://dailybitcoins.org/ads But looking at the source code i cant find how they are doing it. Thanks Joe Link to comment https://forums.phpfreaks.com/topic/246429-textbox-with-instant-update-value/ Share on other sites More sharing options...
