[jQuery] failing miserably in IE

[pedalpete]

I'm not sure where to even start with this.
I've got a page with a ton of scripts that I've basically copied from
one of my other pages (which works fine in IE).

Of course, some of the scripts have changed, but I've got strange
things failing everywhere.
The common errors I was getting an 'undefined error in
jquery-1.3.1.js' error, and i pinned it down to this bit of code

[code]
$('span#datePickers').DatePicker({
        flat: true,
        date: Date(),
        current: multiCalDate(),
        calendars: 3,
        mode: 'range',
        starts: 1,
        onChange: function(formated, dates){
                var theseDates = dates.toString();
                var splitRange= theseDates.split(',');
                var firstRSplit=splitRange[0].split(' ');
                var firstRange = [
                                        firstRSplit[0],
                                 firstRSplit[1],
                                firstRSplit[2],
                                firstRSplit[3].length == 4 ? firstRSplit[3] : 
firstRSplit
[5],
                                 ''
                                        ].join(' ');

        var secondRSplit=splitRange[1].split(' ');
        var secondRange =               [
                                        secondRSplit[0],
                                 secondRSplit[1],
                                 secondRSplit[2],
                                secondRSplit[3].length == 4 ? secondRSplit[3] : 
secondRSplit
[5],
                                 ''
                                        ].join(' ');

        if(firstRange==secondRange){
        var dateRange=firstRange;
        } else {
        var dateRange = firstRange+' to '+secondRange;
        }
        jQuery('.updateDate').html(dateRange);
        jQuery('.updateDate').attr('id',formated)
        }
});
[/code]

again, i don't know why this is, and this code works without issue.

So I removed this bit of code, and now I can get the page to load, but
my trying to make an ajax request with

[code]
 jQuery('div#holdShows ul.showList').livequery(function(){
     jQuery.ajax({
      type: "GET",
      url: "processes/formatShows.php",
      data: "output=&genre="+genre+"&numDays="+numDays
+"&numResults="+numResults+"&date="+toDate+"&dateRange="+dateRange
+"&range="+range+"&lat="+lat+"&long="+long,
      success: function(response){
    alert(response);
        jQuery('div#holdShows ul.showList').html(response);
        }
        });
                });
[/code]

does not launch the alerts, at all.
Of course, running this page in FF or Chrome results in no errors and
everything runs smoothly.

I've been at this for days trying to get it to work.
Please, please, please!!! How would you go about working through this?

I'm using debugbar in IE for debugging. I'm on Vista Home version, so
the debugging tools are limited.
Thanks,
