Unload clip with a button in the loaded clip

Hi and thanks everybody for a great forum!:disco:

So I want to Unload a clip with a button placed in the loaded clip.

First I have this code for my preloader and movieclip loader:

var mcl:MovieClipLoader = new MovieClipLoader();

var mclL:Object = new Object();

mclL.onLoadProgress = function(target,loaded,total) {
loader.percent.text = Math.round((loaded/total) * 100) + “%”;
}

mclL.onLoadInit = function() {
loader._visible = false;
loader.percent.text = “”;
}

mcl.addListener(mclL);

** And this code on my button to load the clip into holder:**

loadClipBtn.onRelease = function() {
loader._visible = true;
mcl.loadClip(“start.swf”,holder);
}

And then when my start.swf file has loaded into holder, I want to be able to remove it from holder, with a button placed on start.swf.

** Ive tried this code for the button in start.swf**, it doesnt work there, i think its something with the path?

removeClipBtn.onRelease = function() {
mcl.unloadClip(holder);
}

Help is Much appreciated:sure:
Thanks
