require first and last name at registration

I’ve tried to add several plugins to handle the extra two fields I want new users to fill out, but without success. I guess the registration page that “memberhip” uses is now different then the original wordpress registration page.

After deleting the Registration page created b Membership, logging in with the worpress registration did not connect to the subscription level needed.

The reasonI need First and Last name in the registration is that I want to connect my moodle site to the wordpress database and eliminate the user to have to enter their additional information when I move them to moodle..

Please let me know how I can add that reuirement to the registration page
