Actionscript 3: Delete code-generated movieclips when changing frame -

this code generates airport symbol part of bigger presentation. works pretty well, @ moment objects don't disappear when change frame, them to.

i've tried different methods in other frame, whatever error: "call possibly undefined method removechild through reference static type class."

i'm pretty new as3, keep in mind :)

thank you. below code.

for (var key:object in airports)  { var myairport = new airport(); myairport.x = airports[key]["x"]; myairport.y = airports[key]["y"]; myairport.width = 17; myairport.height = 17; addchild(myairport) myairport.addeventlistener(mouseevent.click, this.clickhandler)  } 

put movieclips each scene array build each scene. can loop through array , remove them calling cleanup function:

function cleanupview():void {     for( var i:int = 0; < collectedmovieclipsarray; i++ )     {         var parentcontainer:movieclip = collectedmovieclipsarray[ ].parent movieclip;         parentcontainer.removechild( collectedmovieclipsarray[ ] );     } } 

the as movieclip part not necessary.
