Hi, I intend to use Login Manager for user authentication to archive folder on my website. Then I was able to lay my hands on a sample written by dlpierson : Login Manager with an SQL database; http://www.zope.org/Members/dlpierson/sqlLogin I followed this strictly but when I was about to test it, I was experiencing problem with this particular Z MySql Method SQL_add_use. The Method has 3 arguments :(member_id, password, member_email). INSERT INTO member_authorization VALUES (<dtml-sqlvar member_id type=string>, <dtml-sqlvar password type=string>, <dtml-sqlvar member_email type=string>) <dtml-var sql_delimiter> INSERT INTO member_role_map VALUES (<dtml-sqlvar member_id type=string>, 'Member') <dtml-var sql_delimiter> INSERT INTO member_statistics VALUES (<dtml-sqlvar member-id type=string>, NULL, NULL) <dtml-var sql_delimiter> INSERT INTO member_profile VALUES (<dtml-sqlvar member_id type=string>, NULL, NULL) SQL used: Could not render the query template!
