title: Corona SDK director class passing variables between scenes
body: <p>I am trying to pass variables between scenes using the director class in Corona SDK but it wont work. What I need to do is give a set of options for the user i.e button 1, button 2, button 3. If the user selects button 1 then I need to pass a variable to the next scenes to access through an if statement. So if button 1 then display blue.jpg, if button 2 display yellow.jpg. I would really appreciate help with this. Thanks. </p>
