Conflict between jquery and prototype

Question

I am using prototype and jquery, plus I'm creating a slide with another plugin which requires jquery. Now try jQuery.noConflict () , but still does not work.

var $j = jQuery.noConflict();
$j(document).ready(function(){
    $j('#slides').slides({
        play: 5000,
        pause: 2500,
        hoverPause: true
    });
});

This is the error that gives me the chrome and it does not work the slide.

Uncaught RangeError: Invalid array length

Is this a problem of variable scope? Did you tried removing the "var" next to j to declare j as global? Hope that helps.
