    var formObj = document.forms[formName];
    var formEl = formObj.elements;
				
    for (var i=0; i<formEl.length; i++){
        var element = formEl[i];
					
        if (element.type == 'submit') { continue; }
	if (element.type == 'reset') { continue; }
	if (element.type == 'button') { continue; }
	if (element.type == 'hidden') { continue; }
					
	if (element.type == 'text') { element.value = ''; }
	if (element.type == 'textarea') { element.value = ''; }
	if (element.type == 'checkbox') { element.checked = false; }
	if (element.type == 'radio') { element.checked = false; }
	if (element.type == 'select-multiple') { element.selectedIndex = -1; }
	if (element.type == 'select-one') { element.selectedIndex = -1; }
    }
