Remove or translate Send me a copy

Hello,

I need to translate the message “Send me a copy” or remove the option.

I edited salesforce.php with this code:
$options[‘showccuser’] = false;
$options[‘ccusermsg’] = __(‘Enviarme email a mi’,’salesforce’);

After that I refreshed the page and nothing happens.

I have translated more options, for example:
$options[‘submitbutton’] = __(‘Enviar’,’salesforce’);
And the translation is correctly, but for “Send me a copy” is not working.

Thx in advanced
