rewrites and custom links in page need help with add_rewrite_rule

Internal rewrite rules should all point to index.php. You also need to set the proper query vars so that the main query can successfully run, in this case, to query for your detail page.

add_rewrite_rule(
    'detail/([^/]*)/([^/]*)/?$',
    'index.php?pagename=detail&value1=$matches[1]&value2=$matches[2]',
    'top'
);
