You can't return more then 1 value.

pawn Код:

if(PlayerInfo[playerid][WHack] == 1)
    {
        print("Admins Aware");
        PlayerInfo[playerid][WHack] = 2;
        return 1;
    }

    if(PlayerInfo[playerid][WHack] == 2)
    {
        Kick(playerid);
        SendClientMessage(playerid, red, "You been kicked for Weapon hacks, this means you had warning next is ban");
        PlayerInfo[playerid][WHack] = 3;
        return 1;
    }

    if(PlayerInfo[playerid][WHack] == 3)
    {
        Ban(playerid);
        SendClientMessage(playerid, red, "You been banned for Weapn Hacks, This means u been warned and kicked.");
        return 1;
    }

Also, I hope you have a way to link 'playerid' with their IP or name, because I assume once they rejoin from being kicked theyir WHack will be 0.
