В 12-ой строке вижу только var elem = elems[i],

function savecook() {
var sel = document.getElementsByTagName('select');
var i;
            for (var i=0; i < sel.length; i++) {
                var sel = sels[i],
                    b = getCookie(sel.name);
                sel.selectedIndex = b !== undefined ? c : 0;

	};
      
        window.onload = function () {
            var elems = document.getElementsByTagName('select');
            for (var i = 0; i < elems.length; i++) {
                var elem = elems[i],
                    c = getCookie(elem.name);

                elem.selectedIndex = c !== undefined ? c : 0;
            }

        }
    </script>
