php - label of repeat password symfony 2.3 -

I am trying to create a form with Symphony but I have a problem with the repetitive field < Pre> - & gt; Add ('password', 'repeated', array ('type' = & gt; 'password', 'first_name' => $ translator- & gt; trans ('global.password'), 'second_name' = & Gt; $ translator- & gt; trans ('register.confirm'))

If a place is just one word in first_name or second_name but I have no problem or a point I have this error:

  The name "register.confirm" contains invalid characters. The name must start with a letter, number, or underscore and it only contains letters, numbers, numbers, under Scores ("_"), hyphen ("-") and colon (":") are included. Labels are not labeled for    = "text"> 
  first_name  and  second_name  fields. These are the  names  of the area and  letters, numbers, numbers, underscores ("_"), hyphen ("-") and colon (":")  Nothing should be left except For more information, see the isValidName method source code:  
 For both fields use  first_pop  and  other options /  to label   to determine.
