title: function onOpen() is not running
body: <p>My function includes adding a menu and toast to the document. I have verified that the trigger (onOpen) is set as well. It only works when a user goes into Tools, Script Manager, Run. We have too many users with too many backgrounds to expect then to know how to do this. Why isn't it working? (Using Chrome)</p>
  
  <pre><code>function onOpen()
  {
    var menus = [{name: "Advance in Workflow", functionName:"sendEmail"}];
  
       SpreadsheetApp.getActiveSpreadsheet().addMenu("Auto Advance FG Workflow", menus);
  
    //sheet.toast(Notify/Remind users);
     sheet.toast("While you are here we kindly ask that you do not add, modify or remove     any columns.","Welcome - " + username,8);
   }
  </code></pre>
  
  <p>Thanks, </p>
