function clickclear(thisfield, defaulttext, color) {
        if (thisfield.value == defaulttext) {
                thisfield.value = "";
                if (!color) {
                        color = "000000";
                }
                thisfield.style.color = "#" + color;
        }
}
function clickrecall(thisfield, defaulttext, color) {
        if (thisfield.value == "") {
                thisfield.value = defaulttext;
                if (!color) {
                        color = "cccccc";
                }
