title: ReferenceError: Error #1069: Property running not found on flash.media.SoundChannel and there is no default value. - Simple Music "Button"
body: <p>I have a little music button that when clicked stops a music channel, and when clicked again plays it. It starts of playing and when I click it I get an error:</p>
  
  <p>Here is the full error:</p>
  
  <pre><code>ReferenceError: Error #1069: Property running not found on flash.media.SoundChannel and there is no default value.
      at [PROJECTNAME]::MainTimeline/fl_TapHandler_8()[Rockfall_fla.MainTimeline::frame3:215]
      at runtime::ContentPlayer/simulationSendTouchEvent()
      at runtime::SimulatedContentPlayer/clientSocketDataHandler()
  </code></pre>
  
  <p>Frame 3 line 215 refers to this line of code:</p>
  
  <pre><code>if(Chn_musicLoop.running == true){
  </code></pre>
  
  <p>The small function that deals with the music looks like this:</p>
  
  <pre><code>function fl_TapHandler_8(event:TouchEvent):void
  {
      if(Chn_musicLoop.running == true){
      musicIcon.alpha *= 0.5;
      Chn_musicLoop.stop();
      }
      else{
          musicIcon.alpha *= 2;
          Chn_musicLoop.play()
      }}
  </code></pre>
  
  <p>Is there something I'm missing? When I click "<code>dismiss</code>" on the text box, it stops the music like it should... </p>
