  It's fine for you to ask questions in the Q&A, but when someone has helped, remember to do your part by marking the best answer to close the post.

  Anyway, I think you nearly there, with your code. Try this:

  app.js:

  var win_login=Titanium.UI.createWindow({
      url:'wins/login.js',
      title:'Login',
      backgroundColor:'#CCC',
      navBarHidden:true
  });
  win_login.open();
  

  login.js

  var win = Titanium.UI.currentWindow;
  
  var login=Titanium.UI.createButton({
      title:'Login',
      width:250,
      top:330
  });
  win.add(login);
  
  var signUp=Titanium.UI.createButton({
       title:'Sign-up',
       width:250,
       top:330
  });
  win.add(signUp);
  
  
  var win_signUp=Titanium.UI.createWindow({
      url:'wins/signUp.js',
      title:'Sign-up',
      backgroundColor:'#CCC',
      navBarHidden:true
  });
  
  login.addEventListener('click', function(e){
      win_signUp.open();
  });
  

  signUp.js:

  var win = Titanium.UI.currentWindow;
  // add your signup screen views and logic here
  

  Remember javascript is case sensitive, so watch for misspelled vars etc!
