jquery - Required attribute not letting vb code run -

currently doing web forms asp.net. site run hiding , showing divs. i'm working on help desk area. there couple of drop downs selects type of problem have , makes right questions visible, changing div visible. parts mandatory when div shown , others not. illustration of in 1 of divs:

customer #: <input type="text" name="customer_number" required="" /><br />

the button @ end of divs run @ server , have breakpoint right away. way can breakpoint if take out required part of each input. know why problem, , how prepare it?

edit:

wow figured out. had wrong problem. using required="" works problem have other required things hidden. button click doesn't work because hidden ones still required. i'll have come work around
