I’m stumped on this…  
I have a function that I want to use to change either the \_x and \_y or the \_width and \_height. Rather than writing a separate function for each.

For example, instead of writing this…

```auto
 function changeMC(clip) { 
	 clip._x = 50;
	 clip._y = 50;
}

```

I want it to work kinda like this…

```auto
 function changeMC(clip, unitA, unitB) {
	 clip.unitA = 50;
	 clip.unitB = 50;
}
// and I'd call it with something like...
 
changeMC(this, _width, _height); // OR......
changeMC(this, _x, _y);

```

My problem is, when I call the function as I wrote it above, Flash naturally takes the \_width and \_height Values (ie. 432, or whatever the width and height may be), instead of literally putting ‘\_width’ or ‘\_height’ where the params are found throughout the function…

Hope that made sense 🙂 If not I’ll try to elaborate.  
Thanks!
