[help] /revive command dosen´t exist

Like the /revive command dosen´t exist. It worked before. I want it to work like admins can do /revive but no one else can. It doesnt eaven show any errors. And when there comes the hold [E] to respavn and you press e it revives you in the same place where you died.
(sorry for bad english)

Are u using exs_ambulance ?

can’t really help without any code either, and the question above aswell, please share.
