Problems addressing a button in a movie clip

programming flash
1

Hi

I am trying to target a button contained within a movie clip that i am dynamically loading from the library. I am loading the clip with the following code,

var newClip:MovieClip = container_mc(“container”);

function loadReservation ():Void
{
attachMovie(“container_mc”, “container”, 0);
removeMC(defaultContent_mc);
container._y = 150.8 ;
container._x = 10;
}

That loads the movie clip fine.

Then i am trying to target a button (closeResDetailsBtn) inside the container movie clip (that is now on stage). I have tried the following

container.closeResDetailsBtn.onRelease = function ()
{
trace(“its worked”);
}

and

container_mc.closeResDetailsBtn.onRelease = function ()
{
trace(“its worked”);
}

neither option works, i have also tried creating a variable in my code for the button with

var newButton:Button = closeResDetailsBtn(“close”);

and using

close.onRelease = function ()
{
trace(“its worked”);
}

Basiclly i need the button closeResDetailsBtn to close the container movie clip.
Does anyone know what i am missing please?

Cheers

Liam.
