[jQuery] Effect Issue in IE

[jQuery] Effect Issue in IE


Hi,
I have given the example code is below,
function showDiv(divid){
        $("#"+divid).show("slow");
    }
function hideDiv(divid){
        $("#"+divid).hide("slow");
    }
<a href="javascript:showDiv('screen')">Test</a>
<div id="screen" style="display:none">
    <div class="cbox">
        <div class="hbg">
            <div class="lft"><img src="images/img1.gif" width="157" height="15"
alt="" /></div>
            <div class="rgt"><a href="javascript:hideDiv('screen')">close [x]</
a></div>
        </div>
        <ul>
            <li>Link1</li>
<li>Link2</li>
<li>Link3</li>
<li>Link4</li>
        </ul>
    </div></div>
Some CSS Classes applied hidden div.
My problem is Animation($("#screen").show("slow")) is not working in
IE6 and IE7 browsers. Anythink wrong this code.
