title: How to control main timeline from external swf
body: <p>I have a main.swf and inside it is just a plain container movieclip. Using the Loader function I load an external swf  called content.swf inside that container. Container.swf has a button inside it.
  Now when external swf is loaded in container mc which is on the main.swf stage, I want to move to another frame by clicking the button of the loaded external swf.
  If I try to control it from the main timeline I get error saying </p>
  
  <pre><code>cannot convert flash.display::Loader@117e7041 to flash.display.MovieClip.
  </code></pre>
  
  <p>If I try to control it from the external swf I can trace the click on the button but timeline doesn't move to the wanted frame.</p>
