title: Google SpreadSheet saving "undefined" values
body: <p>My case is this, I'm Trying to save data or values taken from a form created on GUI Builder, the first time I've used the example script posted on  [link to google script documentation ][1]</p>
  
  <p>It worked good, I was able to take values typed at the form, but when I decided to use the GUI Builder because, we need more text fields and stuff, It stop working, Every time that I click the button, my spreadsheet gets an "Undefined" value.</p>
  
  <p>I've checked all the IDs and all of them are exactly as the script.</p>
  
  <p>The code:</p>
  
  <p>_guardar : This function inserts textfield values to the spreadsheet.
  celda means cell in english
  ultimaFila means lastRow</p>
  
  <pre><code>   function doGet(e) {      
     var doc = SpreadsheetApp.openById('0Au-gVDPWE5-bdDhJQzc2N2U4Q2l3LVY2cWpkbHdXMVE'); 
     var app = UiApp.createApplication();      
     app.add(app.loadComponent("MyForm"));
     return app;
   }  
  
  
  function _guardar(e){
    var app = UiApp.getActiveApplication();
    var doc = SpreadsheetApp.openById('0Au-gVDPWE5-bdDhJQzc2N2U4Q2l3LVY2cWpkbHdXMVE');
    var ultimaFila = doc.getLastRow(); 
    var celda = doc.getRange('a1').offset(ultimaFila, 0); 
    celda.setValue(e.parameter.nombre);
    celda.offset(0, 1).setValue(e.parameter.empresa); 
    celda.offset(0, 2).setValue(e.parameter.nit); 
    celda.offset(0, 3).setValue(e.parameter.sector); 
    celda.offset(0, 4).setValue(e.parameter.telefono); 
    celda.offset(0, 5).setValue(e.parameter.email); 
    celda.offset(0, 6).setValue(e.parameter.web); 
    celda.offset(0, 7).setValue(e.parameter.descripcion);      
  
  
    app.close();
  
    return app; 
  
  }
  </code></pre>
  
  <p>This is similar to the example code at the google documentation site.![enter image description here][2]</p>
  
  <p>Also I've checked that the "OnClick" event ,is it set on "_enviar" function.</p>
  
  <p>All the textboxs and labels are contained in a Absolute panel, including the buttons.</p>
