Problem with goto when calling getChildByName

programming flash
1

hi, I am using new to duplicate a movie clip (blabla). Works fine for .x , .y , etc but when I try gotoAndStop(11), with all the necessary code within that MovieClip, it fails.

Code is as shown below:

import flash.display.*

var posX:int = 0;
var testing = new Array();
for (var i:uint=0;i<10;i++) {
var blabla = new Symbol1();
blabla.x = posX;
posX += 10;
blabla.name = “b” + i;
testing.push(blabla);
addChild(blabla);
}

trace(getChildByName(“b5”) is MovieClip)
//this can work
getChildByName(“b5”).x = 300

/*this cannot work, gives error:
1061: Call to a possibly undefined method gotoAndPlay through a reference with static type flash.display:DisplayObject.
*/

getChildByName(“b5”).gotoAndPlay(20);

Please help!! Thanks! :smirk::smirk:
