I'm trying to update a span tag that is in a fieldset tag that is in a legend tag. The idea is to update the cost of a Software Item as components are selected. The code below works fine if I only have one software item (e.g. - Visual Studio 2008 Pro $2800), but if I add a second item in another fieldset, then when I try to update the span for that fieldset, it updates the span for the fieldset containing my Visual Studio Software. Any ideas what I'm doing wrong?

<script language="javascript" type="text/javascript">
$(document).ready(function() {
    $("li").click(function() {           
        var itemCost = 0;
        $("legend").each(function() {
            var SoftwareItem = $(this).text();
            itemCost = GetItemCost(SoftwareItem);
            $("input:checked").each(function() {               
                var Component = $(this).next("label").text();
                itemCost += GetItemCost(Component);
            });            
            $("#ItemCostSpan").text("Item Cost = $ " + itemCost);
        });
        function GetItemCost(text) {
            var start = 0;
            start = text.lastIndexOf("$");
            var textCost = text.substring(start + 1);
            var itemCost = parseFloat(textCost);
            return itemCost;
        }        
    });
});
</script>

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });
