how to change actionscript 1-2 to actionscript 3-Collection of common programming errors

In flash, I created a button and gave the button this code (in AS1-AS2)

on (release)
{
    gotoAndPlay(5);
    tellTarget("/Anim") //'Anim' is just short form for 'an animation'

    {
        gotoAndPlay(5);
    } // End of TellTarget
}

Since you can’t give specific buttons actions in AS3, I gave the button an instance name (the buttons instance name is now ‘runButton’) and then decided to do this in the actions layer.

runButton.addEventListener(MouseEvent.CLICK, startAnimation);


function startAnimation(event:MouseEvent){

    gotoAndPlay(5);
    tellTarget("/Anim")
    {
        gotoAndPlay(5);
    } // End of TellTarget

}

but it is giving me an error saying that a ‘{‘ is expected after the

function startAnimation(event:MouseEvent):void{

line and it is saying that there is an unexpected ‘}’ on the last line. Any idea how to fix this?

Note: Anim is a movieclip on the main timeline. When I double click the Anim movieclip, it has it’s own timeline. I want that timeline to play along with the main timeline, hence the ‘gotoandPlay(5) and then the other gotoAndPlay after doing ‘tellTarget(Anim’).
