Hey all,

I have a main timeline with the following code:

* * *

import flash.utils.getDefinitionByName;

blackBox.addEventListener(MouseEvent.CLICK, moveTest, false, 0, true);

stop();

var j:Number = 1;  
var topNumber:Number = protArray.length;  
frontProtMovie.protocolNumber.text = topNumber + " Protocols Found";

var bottomNumber1:Number = 1;  
var bottomNumber2:Number = topNumber;  
frontProtMovie.sequenceNumber.text = bottomNumber1 + " of " + bottomNumber2;

for (var i:int = 0; i \< topNumber; i++) {  
var className:String = protArray.pop();  
var classRef:Class = getDefinitionByName(className) as Class;  
var firstOne:DisplayObject = new classRef();  
if(i == 0) {  
firstOne.name = “protocol” + i;  
trace(firstOne.name);  
firstOne.x = 153;  
firstOne.y = 30;  
firstOne.width = 211;  
firstOne.height = 509;  
frontProtMovie.addChild(firstOne);  
} else {  
var spacing:Number = 211 \* i;  
firstOne.name = “protocol” + i;  
trace(firstOne.name);  
firstOne.x = 153 + spacing;  
firstOne.y = 30;  
firstOne.width = 211;  
firstOne.height = 509;  
frontProtMovie.addChild(firstOne);  
}  
}

function moveTest(evt:MouseEvent):void {  
var wanted:DisplayObject = getChildByName(“protocol0”);  
wanted.x -= 50;  
}

* * *

I keep getting a 1009 error whenever I click the blackBox. Am I not naming the instances of my “firstOne” object correctly? The firstOne object is nested inside the “frontProtMovie” movie clip.

:crying:
