[jQuery] Defining more than one function

[jQuery] Defining more than one function

I am trying to define three functions within the $(document).ready() function. However, each of these functions only work if the other two are not there. I have to use noConflict mode because I am also using Protype as well. What is the proper syntax to define more than one function? Here's what I have right now:
<script type="text/javascript">
    var J = jQuery.noConflict();
    J(document).ready(function(){
        J('#slickbox').hide('slow');
       
        J("#next").click(function(){
            J("#1201410000").hide(10000)
            J("#1201496400").hide(10000)
            J("#1201582800").hide(10000)
            J("#1201669200").hide(10000)
            J("#1201755600").hide(10000)
            J("#1201842000").hide(10000)
            J("#1201928400").hide(10000)
            return false;
        });
       
        J("#previous").click(function(){
            J("#calendar").append('<h1>this is a test</h1>');
            return false;
        });
    });
</script>
