Hello, I am making an Bank System, but I need help in something to finish it.
I have tried almost everything but I can't get the Bank Username to check OnPlayerDisconnect callback if the dini exists.

pawn Code:

// OnDialogResponse
        case DIALOG_BANKCREATE: // Create Bank Username
        {
            if(!response) return ShowPlayerDialog(playerid, DIALOG_BANKMAIN, DIALOG_STYLE_LIST, "{FFFF00}Bank Account", "Create Bank Account\nLogin Bank Account", "Select", "Cancel");
            if(response) {
                new Rstr[128], Name[MAX_PLAYER_NAME];
                GetPlayerName(playerid, Name, sizeof(Name));
                format(Rstr, sizeof(Rstr), BankFile, inputtext);
                if(dini_Exists(Rstr)) return SendClientMessage(playerid, COLOR_RED, "This Bank Username is already registered. Please try with another Username!") && ShowPlayerDialog(playerid, DIALOG_BANKCREATE, DIALOG_STYLE_INPUT, "{FFFF00}Bank Account", "Create Account Username:", "Ok", "Back");
                SetPVarString(playerid, "Username", Rstr);
                dini_Create(Rstr);
                dini_Set(Rstr, "Name", Name);
                dini_IntSet(Rstr, "Registered", 1);
                dini_IntSet(Rstr, "Money", 0);
                return ShowPlayerDialog(playerid, DIALOG_BANKCREATEPASS, DIALOG_STYLE_INPUT, "{FFFF00}Bank Account", "Create Account Password:", "Ok", "Back");
            }
        }
        case DIALOG_BANKCREATEPASS: // Create Bank Password
        {
            if(!response) return ShowPlayerDialog(playerid, DIALOG_BANKCREATE, DIALOG_STYLE_INPUT, "{FFFF00}Bank Account", "Create Account Username:", "Ok", "Back");
            if(response) {
                new name[64], buf[129];
                GetPVarString(playerid, "Username", name, sizeof(name));
                WP_Hash(buf, sizeof(buf), inputtext);
                dini_Set(name, "Password", buf);
                BankSettings[playerid][BANK_REGISTERED] = 1;
                return ShowPlayerDialog(playerid, DIALOG_BANKSETTINGS, DIALOG_STYLE_LIST, "{FFFF00}Account Settings", "Balance\nWithdraw\nDeposit\nTransfer\nChange Account Password\nDelete Account", "Ok", "Back");
            }
        }
Players are able to create a Bank Username and a Bank Password.
I have set PVar to Get the Bank Username on the Dialog about Password.
The username is totally different with Player's Name.

pawn Code:

// OnPlayerDisconnect
    // ** Save Bank Account's Money ** //
    format(str, sizeof(str), "Admin/BankAccount/%s.ini", GetPVarString(playerid, "Username", str, sizeof(str)));
    if(dini_Exists(str)) {
        dini_IntSet(str, "Money", BankSettings[playerid][BANK_MONEY]);
    }
I have tried to get the Bank Usernamefrom the PVar I set it before and check if the file exists on the File Location.
But it's doesn't work. It doesn't save the money.
How can I get the Bank Username and set it OnPlayerDisconnect to check if the file exists, to continue by saving the money.
