I'm not sure, but I think you can't put inline JavaScript within a <script> tag that also has a src attribute.

Maybe try:

<script type="text/javascript" src="mootools-1.2.1-core-yc.js"></script>

<script type="text/javascript" src="MooCrop.js"></script>

<script type="text/javascript">

    window.addEvent('load',function(){

       var crop new MooCrop('crop_example1'); 

    });   

</script>

Ah, just noticed your call to the MooCrop function is faulty. Forgot the = sign:

var crop = new MooCrop('crop_example1');

I added the "=" now it gives the error "Microsoft JScript runtime error: Object doesn't support this property or method"

this is line 32 of MooCrop.JS

Line is highlighted "if ( this.img.getTag() != )  return fasle

Hmm, never heard of a method named getTag(), could be a mootools element extension...
you could try changing this.img.getTag() to this.img.tagName.toLowerCase()
All it does is checking if it's an image tag or not..
