Movie clip not visible

Question

I the code below I want to add the following array of movie clips: activeLevelofTilesArray
After I added the code below the swf plays with the following error:
ReferenceError: Error #1069: Property [object S],[object T],...etc.
not found on builtin.as$0.MethodClosure and there is no default value.
    at WordArray/startTileTimer()
    at WordArray/activeLevelofTiles()
    at WordArray/tileGenerator()
    at WordArray/levelGenerator()
    at WordArray()
    at wordText/initWordText()
    at flash.display::DisplayObjectContainer/addChild()
    at BugGoopFSGame/startTimer()
I can also not see the movie clips.
To try to trouble shoot this I ran a trace statement successfully and I turned off any graphics that might be in front of it. Why can't I see my movieclips and how do I fix error 1069?

Hi Ned,
Thanks, I moved the shuffle function out of activeLevelofTiles like you said and it still works. Yippeeeee
I have 3 more issues that I need to sort out:
I'm not doing this whole tile business correctly. As you predicted - If I trace the tile_index value I see only one tile eg. [object a]. It gives me a different one every time so I know the suffle function still works. I need for it to shuffle through the entire active level *3 so that "the tiles fall from the sky" individually generated by the timer that I have built. I guess I have to add it to an event handler.
Although the trace (activeLevelofTilesArray[tile_index]); worked, I still can not see even the one object generated in the swf file - I think this will solve itself when issue 3 is solved
After I descovered issues 1 and 2 above, I attempted to declare the tile_index variable outside of the loop. I must have done it wrong or incompletely because I get the following error messages on all the lines I used tile_index:
                         1120: Access of undefined property tile_index.
Below is the code now:
function tileIndex():void   //this must be wrong because it gives me that error code and as you predicted only gives one value (I want te whole lot times 3)
                                for (var i: Number  =0; i < activeLevelofTilesArray.length*3; i++)
                            var tile_index = (i%activeLevelofTilesArray.length);
                    function activeLevelofTiles():void
                        activeLevelofTilesArray = letterLevels.shift();
                        shuffleTiles(activeLevelofTilesArray);
                            tileTimer.start();
                            trace(activeLevelofTilesArray);
                            activeLevelofTilesArray[tile_index].x = 399;
                            activeLevelofTilesArray[tile_index].y= 30;
                            addChild (activeLevelofTilesArray[tile_index]);  //maybe the addChild will work (issue 2) when the tile_index problem is solved
                            trace("Letters should run");
                            trace (activeLevelofTilesArray[tile_index]);
