Incorrect language warning error massage

Good afternoon,

When I have checked my HTML code in W3C Validator, a language error appears.. This error says that the language is incorrect because the validator consider my code as Catalan, but my code was written in Spanish from Spain. 

Could you show me any answer to write this HTML lang tag correctly?

Kind regards.
