It still won't save anything in the vault

all that is in the vault:
Thank you all, but shouldn't
PHP Code:
client_cmd(id, "messagemode RRM_ChangeRule");
client_print(id, print_chat, "Write the %s. rule.", key);
be
PHP Code:
client_cmd(id, "messagemode RRM_ChangeRule", key);
client_print(id, print_chat, "Write the %s. rule.", key);
? or else, how should it get the 2. arg?
And
PHP Code:
client_print(id, print_chat, "Write the %s. rule.", key);
only says: "
Write the" ingame
