toggling problem

[gilgalbiblewheel]

I'm trying to toggle a form. What's wrong with this?

    <script type="text/javascript" language="javascript1.3">
            function toggle(id){
                ol = "ol_" + id;
                img = "img_" + id;
                olElement = document.getElementById(ol);
                imgElement = document.getElementById(img);
                if (olElement){
                        if (olElement.className == 'closed'){
                                olElement.className = "open";
                                imgElement.src = "images/opened.gif";
                                }else{
                                olElement.className = "closed";
                                imgElement.src = "images/closed.gif";
                                }
                        }
                }
        </script>
        <a  onclick="toggle('item1');">    
            <h5><img src="images/closed.gif" alt="Click to Expand" id="img_item1" border="0" /> Email it to Someone</h5></a>
