[Uncaught ReferenceError: TweenMax is not defined]

Thank you Jonathan, this was fixed

[Uncaught ReferenceError: TweenMax is not defined]

Howdy!

First of all let me apologize if this is issue has been dealed before, I couldn't find out where

 

Well, this is my trouble:

I followed the tutorial in this url, but I can't manage TweenMax and get this error: Uncaught ReferenceError: TweenMax is not defined

 

I load this libraries at the markup's bottom:

        <script src="jquery-1.9.1.min.js"></script>

        <script src="TweenLite.min.js"></script>

        <script src="TweenMax.min.js"></script>

        <script src="EasePack.min.js"></script>

        <script src="CSSPlugin.min.js"></script>

        <script src="main.js"></script>

The main.js has this:

 

$(document).ready(function(){

        animPieza1();

}

 

function animPieza1(){

        var pieza1 = $("#html1_pieza1b");

        TweenMax.to(pieza1, 1, {opacity:0, repeat:-1, yoyo:true});

}

 

Any idea?

 

Best!
