hi there,  
I’m having trouble. I want to create a function that can create new MCs. I have a movieClip exporting as “Box” in my library, and I want to add an instance to the stage called “box”…

like so:

```auto

function addNewMC (instanceName:String, mcName:MovieClip)
{
    instanceName:mcName = new mcName;
    addChild(instanceName);
}

addNewMC(box, Box);

```

but that does not work! I think it’s something small, but I’m not sure what. I’m going to use this function for a bunch of different MCs, which is why I want it to by dynamic.

If there’s a smarter way to do this… I will!  
Thanks! -Travis
