i'm still new in jquery, i need to validate the field within fieldset dynamically without calling specific Id.

here is my code jSfiddle

As you can see, on the 1st page, when click continue, error on the 2nd page also will enable because on the part i pass the variable on visible fieldset still not success.

any idea to solve this issue? and please suggest the improve code to eliminate repeating line of same code.

I cannot use available jquery plugin because in my code have select list which is use ul li style not select option method.

Thanks in advance
