Chockbox with rolldown selection

Hi i have a form on one of my sites were im using radio buttons to make a selection, when a radiobutton is selected a selection menu fir that menu falls down.

My problem is that the first selection of either menu is sent with the form, how can I choose to only send the one I select ( hope you know what I mean )

If i press left button and choose an option from left menu, the top choice of right menu will follow.
I have put a form with only these options here : http://prag2015.se/boka-nu/

CODE for contact form:

<table style=”text-align: left;”>
