Question

I created this script to be able to send an email after a grid has been filled with information. Before the email is sent, another display comes in an warns the user to continue only if the information is correct. At the end the script sends an email to me, with the info entered by the user. The problem is here, when I received the email, the fields that the script is suppose to replace are shown as undefined and no info is there. Any ideas on what is wrong here??
Thank you!

function runmyapp() {
 var doc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setTitle('Title 1');
  var grid = app.createGrid(4, 5);
  grid.setWidget(0, 0, app.createLabel('Time '));
  grid.setWidget(0, 1, app.createTextBox().setName('Time'));
  grid.setWidget(1, 0, app.createLabel('Minutes'));
  grid.setWidget(1, 1, app.createTextBox().setName('Minutes'));
  grid.setWidget(2, 0, app.createLabel('Enter Name'));
  grid.setWidget(2, 1, app.createTextBox().setName('Name'));
  grid.setWidget(3, 0, app.createLabel('Email'));
  grid.setWidget(3, 1, app.createTextBox().setName('email'));
  var panel = app.createVerticalPanel();
  panel.add(grid);

  var button = app.createButton('Submit').setId("button");
  var handler2 = app.createServerHandler('dis');
  handler2.addCallbackElement(grid);
  button.addClickHandler(handler2); 
  var handler = app.createServerHandler('disc');
  handler.addCallbackElement(grid);
  button.addClickHandler(handler);   

  // Add the button to the panel and the panel to the application, then display the                              application app
    panel.add(button);
    app.add(panel);
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);
  }

function dis(e){
 var app = UiApp.getActiveApplication();
   app.getElementById("button").setText("Request is in process, please     wait!").setEnabled(false);
   return app;
   }; 

function disc(e){
   var app = UiApp.getActiveApplication();
   var html1 = app.add(app.createHTML("<p><p>Hello Expert,</p>"+
"<p>By clicking OK you agree that your information is correct</p>");
    var button = app.createButton('Ok').setId("button");
    app.add(button);
    var handler2 = app.createServerHandler('gsnot');
    button.addClickHandler(handler2); 
    var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);
  return app;}




  function gsnot(e) {
    var advancedArgs = {bcc:e.parameter.email};
    var emailSubject = "Subject";
    var address ="[e-mail]";

    var emailTemplate     =SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Templates").getRange("A1").getValue(    ) ; 
    emailTemplate = emailTemplate.replace("TIME", e.parameter.Times).replace("MIN",     e.parameter.Minutes).replace("EXP", e.parameter.Name);   

    MailApp.sendEmail(address, emailSubject, emailTemplate, advancedArgs);

    Browser.msgBox("Your Email has been sent!");

    var app = UiApp.getActiveApplication();
    app.close();
    // The following line is REQUIRED for the widget to actually close.
    var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);
  }

To make a widget value show on your e.parameter you need to add it (or a parent panel) as a callback element on the handler. Like this:

function runmyapp() {
  //...
  var grid = app.createGrid(4, 5).setId('grid');
  //...
}

function disc(e){
  //...
  var grid = app.getElementById('grid');
  var handler2 = app.createServerHandler('gsnot').addCallbackElement(grid);
  //...
}
