title: show/hide dropdown menu depending on radio button selection - jquery
body: <p>I have made a form with 2 radio buttons and 2 drop down menus which works.
  however i have now added another 2 radio buttons and 2 more drop down menus ( i have not changed the jquery) so it is not working.</p>
  
  <p>i have uploaded it to jsfiddle: <a href="http://jsfiddle.net/qbawh/" rel="nofollow">http://jsfiddle.net/qbawh/</a></p>
  
  <p>what do I need to change in the jquery for both radio buttons and dropdowns to work.</p>
  
  <p>what the form should do is:
  if 'no' is selcted on 1 i want the dropdown to be greyed out. if 'yes' is selected users can select from dropdown. I want both to work independtly.</p>
