<HEAD>
<SCRIPT>
function fnCheck()
{
    // Retrieve number of top-level items
    var nTopItems = oToolBar.numItems;
    // Check each item to see if it is a toolbarCheckGroup item
    var i, oSelectedCheckbox;
    for(i=0; i<nTopItems; i++)
    {
        var oItem = oToolBar.getItem(i);
        if(oItem.getType()== "checkgroup")
        {
           // Retrieve number of checkbuttons in checkgroup
           var nCheckButtons = oItem.getCount();
           // Display the text of each checkbutton in the checkgroup
           var j;
           for(j=0; j<nCheckButtons; j++)
           {
