I think that you forgot some brackets, anyway try this one,

pawn Код:

if(strcmp(cmd, "/pay", true) == 0)
{
    if(IsPlayerConnected(playerid) && (boxevent == 0) && if (PlayerInfo[playerid][pAdmin] >= 1337))
    {
        boxevent = 1;
        BroadCast(COLOR_GREEN, " ***************!");
    }
    else if(IsPlayerConnected(playerid) && (boxevent == 1))
    {
        if(IsPlayerAdmin(playerid))
        {
            boxevent = 0;
            BroadCast(COLOR_GREEN, " ******************.");
        }
    }
    return 1;
}
