</html>My problem is I append a text when I click checkbox but when I unselect it back then it does not shows the old original one value I have already tried the Inner HTML but it does not work because the prices will be dynamic in my case Here it is the code , I want if I unselect the checkbox then i get the old one $40 back, I don't want to append it by inner HTML="$40" because it will be dynamic and the prices will be different in all cases . someone would solve it?
