Married same man twice. 1st in AZ. 2nd in CA. I used the date of the 2nd marriage on divorce only. Does this mean im still married?

As I understand your question, you cannot get married twice without having been divorced from the first marriage. The 2nd marriage would be void as a matter of law. If you got a divorce from said person, I think it's insignificant what date you put down. The divorce should be effective against the person you're divorcing (as you had a valid marriage in place with said person.).
