Jquery Fancybox Error

I've been updating a site and have used the fancybox plug in to display dynamic information data. Works great in every browser apart from IE, where i get 'object doesnt support this property or method' errors. I cant figure out 开发者_如何转开发why, it's driving me nuts. has anyone else expereinced this with IE? Any hints/tips?

I'm using this function -

<script type="text/javascript" src="JS/jquery-1.4.2.min.js"> </script>
<script type="text/javascript" src="JS/jquery.mousewheel-3.0.2.pack.js"> </script>
<script type="text/javascript" src="JS/jquery.fancybox-1.3.1.js"> </script>
$(document).ready(function() {
    $(".clickInfo").fancybox({
        'overlayShow':          true,
        'autoScale':            false,
        'transitionIn':         'elastic',
        'transitionOut':        'elastic'
})});; 
</script> 

called by this -

<a href="CTDef.asp?ind=<%=(Names.Fields.Item("Indicator").Value)%>"    class="clickInfo">click for more info</a>

When I've had this error in IE in the past, it's been because an ID on the page was the same as one of the function names.
