hi,

you did not pass the container parameter in you Fla when adding the class object.

you also forgot to add the parenthesis in this line...

var imageLoader:MovieClipLoader = new MovieClipLoader();


Lastly because the MovieClipLoader passes a parameter anyway (e.g. the target), the extra parameters you add with the delegate function will be appended.

e.g.
Code:
private function output(answer:Number)
{
	trace("ANSWER "+answer +"    "+t)
}
will need to become...

Code:
private function output(target:MovieClip, answer:Number)
{
	trace("ANSWER "+answer)
}
so it's better not to use this method to assign the same function to a MovieClipLoader and a MovieClip.
