I created a registration form with Google Forms. Now I would like to have an alert displayed before the submitter starts filling out data.This is my code:function onOpen() {  FormApp.getUi()      .createMenu('Custom Menu')      .addItem('Show alert', 'showAlert')      .addToUi();}function showAlert() {  var ui = FormApp.getUi();  var result = ui.alert(     'Lorem ipsum',     'dolor sit amet, consectetur adipiscing elit',  ui.ButtonSet.OK);}The triggers were set up. The script works fine but only while a form is in in the editing mode, not in a view mode. Actually I'm the only one who can see the message box. It's not what I meant to ;-). How to show this alert to everyone who is going to fill out my form?
