hey, 2 questions about huds

how can i make cvars show up in the hud? eg mp_timelimit sv_nextmap and stuff? is it the same as hostname? like in amxx.cfg %hostname% so %mp_timelimit% or something?

and why dosen't this work?
Code:
/* Plugin generated by AMXX-Studio */
#include <amxmodx>
#include <amxmisc>
#define PLUGIN "Hud"
#define VERSION "1.0"
#define AUTHOR "Omgitsme"
public plugin_init()
{
register_plugin("Hud", "1.0", "Omgitsme")
}
public client_connect(id)
{
if(!is_user_alive(id))
set_hudmessage(255, 255, 255, 0.70, 0.0, 0, 6.0, 0)
show_hudmessage(id, "Message")
}
i want it to be, so whenever the person is dead. it will show the hud message until there alive, but it dosen't show at all -_-
