Hi, The problem was the way he referenced the field *txCantidad*
It does not work: Container cnCantidad = new Container(new GridLayout(1, 3)).add(btMenos).add( *txCantidad.getText()*).add(btMas); It works: Container cnCantidad = new Container(new GridLayout(1, 3)).add(btMenos).add( *txCantidad*).add(btMas); Thanks for support. -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.
