Google translates form Greek language:
Hello. Although I know enough about technology, I find it hard to find the information I need about my registration. I try to designate my husband as a companion, as he continues to advise the site, but when I send him an invitation, he can not answer his pity, as when he clicks GET STARTED he gets a message that he can not because his own entry ... we have different email.

If your husband allready owns an Airbnb account, it will not work this way.
But you can make him your co-host:
