Add French to English Registration Form

I have a client whose site is in English and is using the GravityForm for his registration. Everything works great. He would like to have this same form in French. When I add the Mail fields I can´t find a way how to give the correct french translations for for the fields.

How do I need to go about doing this?

Thanks for any help. First time GravityForm user :)
