        function comefrom(loca, locacity) { this.loca = loca; this.locacity = locacity; }
        function select() {
            with (document.creator.province) { var loca2 = options[selectedIndex].value; }
            for (i = 0; i < where.length; i++) {
                if (where[i].loca == loca2) {
                    loca3 = (where[i].locacity).split("|");
                    for (j = 0; j < loca3.length; j++) { with (document.creator.city) { length = loca3.length; options[j].text = loca3[j]; options[j].value = loca3[j]; var loca4 = options[selectedIndex].value; } }
                    break;
                }
            }
            document.creator.newlocation.value = loca2 + loca4;
        }
        function init() {
            with (document.creator.province) {
                length = where.length;
                for (k = 0; k < where.length; k++) { options[k].text = where[k].loca; options[k].value = where[k].loca; }
                options[selectedIndex].text = where[0].loca; options[selectedIndex].value = where[0].loca;
            }
            with (document.creator.city) {
                loca3 = (where[0].locacity).split("|");
                length = loca3.length;
                for (l = 0; l < length; l++) { options[l].text = loca3[l]; options[l].value = loca3[l]; }
                options[selectedIndex].text = loca3[0]; options[selectedIndex].value = loca3[0];
            }
        }
