Hi!

Sorry for the oddness of this question.

Is this code Valid? It seems as though it is/should be, but isn’t working

```auto

	thumbholder1.onRollOver = function() { 
		this._alpha = 50;
	}
	
	thumbholder1.onRollOut = function() { 
		this._alpha = 100;
	}

```

It is loaded by this (this loading part works fine):

```auto

thumbholder1.loadMovie(alt1thumb[p], thumbholder1.getNextHighestDepth());

```

Thanks so much…

I’m really not quite sure why I can’t get this to work - these seem to be the problems I have, I can get the more complex part of the code down (loading things from an external xml file into an array etc,) but not the simple things like rollovers, haha.

Thanks for your time guys, even if you arn’t able to help me out.:s:
