i need help with a prototype that calls another prototype… hope u get it

```auto
MovieClip.prototype.tracing = function() {
	trace(this._name+"\
\	hello, how are u doing?");
};
MovieClip.prototype.calling = function(proto) {
	this.proto();
};

```

is that ok?

if it is… how should i call the function “calling”?  
1.- this.calling(tracing)  
2.- this.calling(MovieClip.prototype.tracing)

none of that works

(dont worry if u think this is nonsense, im working with bigger prototypes, this was simplified to show my problem and nothing else)
