title: JavaScript Radio button selection validates fields?
body: <p>I need to use javascript so that when the one radio button is selected nothing happens but if the other one is (for example, other address) it will then validate the following fields;</p>
  
  <p>street
  suberb
  postcode </p>
  
  <p>Whilst I post this, it's probably a similar method, but when I have a checkbox and a textbox how could I make it so that the textbox must not be left empty only if the checkbox is checked... </p>
  
  <p>Thanks everyone!!!! Ask for more details if needed, I'm terrible at explaining things!</p>
