[JJB562]

I fixed all the errors. I would suggest that you indent your code. Also it seems that you copied and pasted that tutorial you provided into your script.

pawn Code:

public OnPlayerDisconnect(playerid, reason)
{
    new INI:File = INI_Open(UserPath(playerid));
    INI_SetTag(File,"data");
    INI_WriteInt(File,"Cash",GetPlayerMoney(playerid));
    INI_WriteInt(File,"Admin",PlayerInfo[playerid][pAdmin]);
    INI_WriteInt(File,"Kills",PlayerInfo[playerid][pKills]);
    INI_WriteInt(File,"Deaths",PlayerInfo[playerid][pDeaths]);
    INI_Close(File);
} // You did this several times. Might be a result of copying and pasting.
    new
        string[64],
        name[MAX_PLAYER_NAME];
    GetPlayerName(playerid,name,MAX_PLAYER_NAME);
    switch(reason)
    {
        case 0: format(string,sizeof string,"{1E90FF}%s {006400}(ID:%d) {B22222}left the battlefield. {006400}(Timed out)",name);
        case 1: format(string,sizeof string,"{1E90FF}%s {006400}(ID:%d) {B22222}left the battlefield. {006400}(Leaving)",name);
        case 2: format(string,sizeof string,"{1E90FF}%s {006400}(ID:%d) {B22222}left the battlefield. {006400}(Kicked/Banned)",name);
    }
    return 1;
}

I would also replace the hashing method you used (ubd_hash) with Whirlpool.

Anyways here's the fixed code.
