Im trying to create plugin. I dont know what to do.

Error in lines 14, 19, 24
// error 092: number of arguments does not match definition

This plugin should create annotation above admin head when round ends, and hide that annotation when new round begins or when he die.

PHP Code:

#include <sourcemod>
#include <sdktools>
#pragma semicolon 1

public OnPluginStart()
{
    HookEvent("round_start", Event_RoundStart);
    HookEvent("teamplay_round_win", Event_RoundWin);
    HookEventEx("player_death", event_player_death, EventHookMode_Post);
}

public Event_RoundWin(Handle:event, const String:name[], bool:dontBroadcast)
{
    ShowADMIN();
}

public Event_RoundStart(Handle:event, const String:name[], bool:dontBroadcast)
{
    HideADMIN();
}

public Action:event_player_death(Handle:event, const String:name[], bool:dontBroadcast)
{
    HideADMIN();
}

ShowADMIN(client)
{
    if (!client && !IsClientInGame(client) && !IsPlayerAlive(client) && CheckCommandAccess(client, "generic_admin", ADMFLAG_GENERIC, true)) 
        {
            new Handle:event = CreateEvent("show_annotation");
            if(event == INVALID_HANDLE) return;
            SetEventInt(event, "follow_entindex", client);
            SetEventInt(event, "id", client);
            SetEventFloat(event, "lifetime", 86400.0);
            SetEventString(event, "text", "ADMIN");
            FireEvent(event);
        }
}

HideADMIN(client)
{
    new Handle:event = CreateEvent("hide_annotation");
    if(event == INVALID_HANDLE) return;
    SetEventInt(event, "id", client);
    FireEvent(event);
} 


And is that line #9 Ok?
