Problems fading a button using setInterval [renamed]

WHAT IS WRONG WITH ME!!??

OK, trying to fade out a button through a function. I’ve done this before but I’m tired and it’s just not happening.

OK, there’s a button named “button” and a movieclip named “fadeThis”. The first frame of the root has the following code in it:

fading = function(image) {
_root[image]._alpha -= 5;
}

And the button, “button”, has the following code in it:

on (release) {
fader = setInterval(_root.fading,10,fadeThis);
}

So WHY does the function fade the entire screen (“fadeThis” AND “button”)??

Thanks

Anyone!? PLEASE help! This is really messin with my head now!

attach a samlpe and someone can have a look…probably something silly you are forgetting cause you are tired…heheh
