	if(strcmp(cmd, "/health", true) == 0)
	{
		new Float:health;
		new string[128];
		GetPlayerHealth(playerid, health);
 		format(string, sizeof(string),"Your HP is at %.1f percent!",health); // sizeof(health) ??? = 5 xD, changed to string
 		SendClientMessage(playerid,RED,string); // You didnt send it to player xD
 		return 1;
	}

The others work but SenClientMessage is wrong

Also tested it and it worked!
