[Moo] Simple problem witth Slide/Toggle effect

[Romain]

Hi, my script beloow doesn't work and I can't figure out why !

window.addEvent('domready', function(){
                function DoSlide(Link){
                        var myDiv = $('cont');
                        var mySlide = new Fx.Slide(myDiv, {mode: 'vertical'});
                        mySlide.toggle();
                }
        });

I also made two mootshells to demonstrate the simple issue.

This script works : http://mootools.net/shell/ggvW5/
But this one doesn't : http://mootools.net/shell/E7ced/

Thanks in advance,
Romain
