I'm not found the right way insert this code.
What is between ?

# Add the following to db.cgi in sub main() between some of the other
# elseif statments:

elsif ($in{'create_order'}) { &html_create_order; }
elsif ($in{'verify_address'}) { &html_create_order; }
elsif ($in{'rectify_address'}) { &html_create_order; }
elsif ($in{'address_OK'}) { &html_create_order; }
elsif ($in{'add_order'}) { &html_add_order; }
elsif ($in{'more_order'}) { &html_view_search; }
elsif ($in{'check_order'}) { &html_check_order; }
elsif ($in{'edit_order'}) { &html_edit_order; }
elsif ($in{'change_order'}) { &html_change_order; }
elsif ($in{'send_order'}) { &html_send_order; }
elsif ($in{'cancel_order'}) { &html_cancel_order; }
