label.appendChild(document.createTextNode("Text Box #"+textNumber+": "));
// Put the textbox inside
label.appendChild(textField);
// Add it all to the form
form.insertBefore(label,afterElement);
return false;

// Remove the last one added
form.removeChild(document.getElementById("txt"+textNumber).parentNode);
textNumber--;
}
