<SCRIPT>
function setElement (id, html) {
if (document.layers) {
var l = document[id];
if (!l.overLayer) {
l.overLayer = new Layer(l.clip.width);
l.overLayer.left = l.pageX;
l.overLayer.top = l.pageY;
l.visibility = 'hide';
l.overLayer.visibility = 'show';
}
l.overLayer.document.open();
l.overLayer.document.write(html);
l.overLayer.document.close();

document.all[id].innerHTML = html;

function changeNow() {
var user = document.aForm.user.value
document.aForm.aField.value = "Welcome "+user+"";
setElement ('someParagraph', document.aForm.aField.value);

var nw = "'";
document.write('<FORM NAME="aForm">');
