jQuery in IE6

jQuery in IE6

I'm having a big issue on some jQuery i've put together for a clients website.
The code seems to fall over in IE6 somewhere in this script, but i cant work out where.

If any of you lovely people could help, i'd grately appreciate it!!           
  1. <script type="text/javascript">


    var ImageContent = '<div id="ImageDiv"><div id="page1"
    style="background:url(images/space.gif); width:400px;height:848px;background-position:400px;display:block;"></div><div id="page2" style="background:url(images/space.gif); width:400px; height:848px; background-position:800px; display:none;"></div></div>';
                       


    $(document).ready(function() {

    //hide the real preview
    $("#previewPlaceholder").hide();

    //insert a new preview
    $("#previewPlaceholder").after(ImageContent)

    });
           
    function pageChange(side, page) {
       
    var pagePosition;

    if(page == 1) { pagePosition = '400px' }
    if(page == 2) { pagePosition = '800px' }
    if(page == 3) { pagePosition = '0px' }
               
    if(side == 'page1') {
    var cssObj = { 'background-position' : pagePosition,
    'display' : 'block'
    }
    $('#page1').css(cssObj);
    $('#page2').css('display', 'none')
    }
       
    if(side == 'page2') {
    var cssObj = {
    'background-position' : pagePosition,
    'display' : 'block'
    }
    $('#page2').css(cssObj);
    $('#page1').css('display', 'none')
    }   
    }
    function StorefrontPostAjaxHook()
    {
    //find the real preview source and href and then set it to the new preview
    var imgs,i;
    $('#vcrControls').hide();
    imgs = document.getElementsByTagName('img');
    for(i=0;i<imgs.length;i++)
    {
    if (imgs[i].className == "formFillingPreview")
    {
    previewImage = imgs[i].src;
    previewImage2 = previewImage.replace('Page=1','Page=2');
    CurrentBGP = $('#page1').css('background-position');
    CurrentBGP2 = $('#page2').css('background-position');

    $('#page1').css('background', 'url('+previewImage+')');
    $('#page2').css('background', 'url('+previewImage2+')');
    $('#page1').css('background-position', ''+CurrentBGP+'');
    $('#page2').css('background-position', ''+CurrentBGP2+'')
    }
    }
    }
                </script>
