[jQuery] newbie plugin question

[echobase]

Hi-

I'm just getting into jQuery plugins and I wanted to do a sort of
'hello world' exercise with a barebones plugin template. My template
code is below but I can't get the console.log statement in the setup()
function to show in a firebug console window. IIf I put a console.log
statement immediately following the top line:

    ;(function($) {
      console.log('hello world');

.....it does work. Can someone please tell me what I'm doing wrong?

I call the plugin like so:

<script type="text/javascript" src="myPlugin.js" >
<script type="text/javascript">
  $(document).ready() {
      $('ul').myPlugin();
  });
</script>


myPlugin.js:

;(function($) {

        $.fn.extend({
                myPlugin: function(options) {
                        return this.each(function() {
                                new $.MyPlugin(this, options);
                        });
                }
        });

        $.MyPlugin = function(element, options) {
                var defaults = {
                        helloText: "hello World"
                }

                this.options = $.extend({}, defaults, options || {});

                this.setup();
        };

        $.extend($.MyPlugin.prototype, {

                setup: function() {
                        console.log(this.helloText);
                }
        });
})(jQuery);
