I am getting this error:

```
Uncaught TypeError: Object [object Object] has no method 'calendricalDate'

```

I am trying to use this [plugin](https://github.com/tobico/jquery-calendrical). The weird thing is that it has been working and just all the sudden it stopped.
Here's the jQuery code:

```
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js' type='text/javascript'></script>
<script src="../js/jquery.calendrical.js"></script>
<script>
    $(function() {
        $('#salida, #llegada').calendricalDate();
        $('#salida_time, #llegada_time').calendricalTime();
    });
</script>

```

And the js file is exactly the same from the website, I just copied and pasted. It might be something really dumb that I may have overlooked, so any help is more than appreciated.
Here's more detailed error:

```
14Uncaught TypeError: Object [object Object] has no method 'calendricalDate'
(anonymous function)              enviotracking.php:14

o.extend.ready                    jquery-1.3.2.min.js:19

```

line 14 on the php file is DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Ok this is weird I have another page which has the same code and it works but I did a breakdown of when was the error happening so I took everything out and started added my code 1 by 1 and I noticed when I add this:

```
<script src="../js/jquery-1.6.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function(){

        $("ul.subnav").parent().append("<span></span>"); //Only shows drop down trigger when js is enabled (Adds empty span tag after ul.subnav*)

        $("ul.topnav li span").click(function() { //When trigger is clicked...

            //Following events are applied to the subnav itself (moving subnav up and down)
            $(this).parent().find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on click

            $(this).parent().hover(function() {
            }, function(){
                $(this).parent().find("ul.subnav").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
            });

            //Following events are applied to the trigger (Hover events for the trigger)
            }).hover(function() {
                $(this).addClass("subhover"); //On hover over, add class "subhover"
            }, function(){  //On Hover Out
                $(this).removeClass("subhover"); //On hover out, remove class "subhover"
        });

    });
</script>

```

Is when my code breaks. But that doesn't happen anywhere else :(
