I have the following code:

```
$this->form->setValidators(array(
    'email'   => new sfValidatorAnd(
        array(
            new sfValidatorEmail(array(), array(
                'invalid' => 'Enter a valid email address.',)),
            new sfValidatorDoctrineUnique(array(
                'model'=>'Users',
                'column'=>'email',
                ), array(
                'invalid' => 'This email is already being used.',
                )),
        ),
        array(),
        array(
                'required' => 'Required',
        )
    ),
//...

```

and when the email is not unique, it returns the following error: `email: This email is already being used.` But I don't want that `email:` in front of the message.  

Is there a way I can stop showing the column name?

Can I get some help?
