Fading in and out issue

programming flash
1

Hey guys: I get one part fading in the way I want, but the other part is not doing anything. I get an error when I run this. Please give me some advice about this?

import fl.transitions.Tween;
import fl.transitions.easing.*;

var mcMovieClip:MovieClip = new MovieClip();
var square:Shape = new Shape();
square.graphics.beginFill(0xFF0000, 0.5);
square.graphics.drawRect(0, 0, 1266, 611);
mcMovieClip.addChild(square);
this.addChild(mcMovieClip);

// Set ups for the fades

function setUpStartFade()
{
    var timIn:uint = setTimeout(startFade(),0);    
}

function setUpEndFade()
{
    var timOut:uint = setTimeout(endFade(),5000);
}


// Acutual Fades
function startFade()
{
    var myTweenAlpha:Tween = new Tween(mcMovieClip, 
                                       "alpha", 
                                       Strong.easeOut, 
                                       1, 0, 3, 
                                       true);    
}

function endFade()
{
    var myTweenAlpha:Tween = new Tween(mcMovieClip, 
                                       "alpha", 
                                       Strong.easeOut, 
                                       1, 0, 3, 
                                       true);
}

//
setUpStartFade();
setUpEndFade();
