[Mecha the Slag]

Hi. I'm making a plugin for L4D versus, and I'm trying to find a way to call victory for the survivors. I've looked through

http://wiki.alliedmods.net/Left_4_Dead_Events

but I have little idea how to use them. I tried doing the following

PHP Code:

victory() {
    new Handle:event = CreateEvent("finale_win")
    if (event == INVALID_HANDLE)
    {
        PrintToChatAll("Event is an invalid handle! GASP");
        return
    }
 
    new String:GameDifficulty[256];
    new String:GameMap[256];
    GetConVarString(FindConVar("z_difficulty"), GameDifficulty, sizeof(GameDifficulty));
    GetCurrentMap(GameMap, sizeof(GameMap));
 
    SetEventString(event, "map_name", GameMap)
    SetEventString(event, "difficulty", GameDifficulty)
    FireEvent(event)
    PrintToChatAll("Event successfully fired!");

} 


and it's being called correctly, but it doesn't actually start the victory screen or anything (only gave me an achievement fff)

Any help appreciated.
