Jquery - Need help with my Selector

I am working on some custom form validation. I need help with my selector.

Here is my ideal solution ( in English ):

1. Get all Elements in #myForm that have a class containing the string "error". Include checkboxes and radio's.

2. For each of those elements:

     a) Check to see if the element has a class of "ok-class".

          [YES] Remove that class

     b) Add class "Errror" to element

     c) Find the very next SPAN element. Remove any classes in this tag. Add Class "span-error"

Thanks! This is a little complex for me. I think I could do this one statement at a time, but to write a "chained" statement is a little out of my league.

Can't wait to see some solution ideas!

I suggest you get all elements with class ok-class and see if the contain error
Why not just validate the inputs based on value as part of your submit function instead of doing so much DOM manipulation?
Michel PlungjanIT ExpertCommented:
Maybe you show the validation?

I agree you need to toggle the classes in the validation, for example

function validate(theForm) {
