Try this, you have this in plus if(sscanf(params,"nd", amount))

PHP код:

CMD:deposit(playerid, params[])
{
    if(IsPlayerInRangeOfPoint(playerid, 2, -2455.4519, 503.9336, 30.0781))
    {
        if(GetPlayerMoney(playerid) < 0) return SendClientMessage(playerid, COLOR_RED, "ERROR:You don't have any money on you!");
        new amount;
        if(sscanf(params,"d", amount)) return SendClientMessage(playerid, -1,"USAGE: /deposit [amount]");
            if(amount < 0 ) return SendClientMessage(playerid,-1,"You can not withdraw money with minus");
    GivePlayerMoney(playerid, -amount);
        pInfo[playerid][Bank]++;
    }
    return 1;
}
CMD:withdraw(playerid, params[])
{
    if(IsPlayerInRangeOfPoint(playerid, 2, -2455.4519, 503.9336, 30.0781))
    {
        if(pInfo[playerid][Bank] < 0) return SendClientMessage(playerid, COLOR_RED, "ERROR:You Don't Have Money In Your Bank Account!");
         new amount;
        if(sscanf(params,"d", amount)) return SendClientMessage(playerid, -1,"USAGE: /withdraw [amount]");
            if(amount < 0 ) return SendClientMessage(playerid,-1,"You can not withdraw money with minus");
        GivePlayerMoney(playerid, amount);
        pInfo[playerid][Bank]--;
    }
    return 1;
}
