Alter function code?!

Hi peeps…good afternoon.

I’m looking to add an element to this function to make my text fade. On (release) of my ‘biog’ button this function starts. But also I need my text on the page to fade from 100 to 0 on release, before this function begins. I’ve tried applying code that i have but can’t get it to wrk. Not sure how these functions work exactly and no matter how much reading I do I can’t get this right.

scrollIt = function() {
this.onEnterFrame=function() {
if (_root.container1.SUB._x>440) {
_root.container1.SUB._x += -30;
} else if (_root.container1.SUB._x>-30) {
_root.container1.PAGE._x += (-40-_root.container1.PAGE._x)/8; _root.container1.SUB._x += (0-_root.container1.SUB._x) /2;
}
else { delete this.onEnterFrame;
}
}
}
