I'm trying to edit all the necessary files to have a "member_telephone" entry into the database.

I've modified these files:

member/view_member.php

member/sql_member.php

member/member_list.php

member/lg_member_en.php

member/form_member.php

template/default/member/view_member.html

template/default/member/member_list.html

template/default/member/form_member.html

template/default/member/home_member.html

The field shows up correctly on the page and take input but after clicking submit it disappears and is not adding this new field into the database.

Any ideas?
