I have a textdraw with a timer:

pawn Code:

new GameMinutes = 14;
new GameSeconds = 59;
new Text:Textdraw0;

Textdraw properties:

pawn Code:

Textdraw0 = TextDrawCreate(86.000000,427.000000,"15:00");
    TextDrawAlignment(Textdraw0,2);
    TextDrawBackgroundColor(Textdraw0,0x000000ff);
    TextDrawFont(Textdraw0,3);
    TextDrawLetterSize(Textdraw0,0.499999,2.000000);
    TextDrawColor(Textdraw0,0xffffffff);
    TextDrawSetOutline(Textdraw0,1);
    TextDrawSetProportional(Textdraw0,1);
    TextDrawSetShadow(Textdraw0,1);

Timer:

pawn Code:

SetTimer("GameTime",1000,1);

Timer function:

pawn Code:

public GameTime()
{
    if(GameSeconds > 0 || GameMinutes > 0)
    {
        GameSeconds--;
        if(GameSeconds <= -1)
        {
            GameMinutes--;
            GameSeconds=59;
        }
        new TimeString[14];
        format(TimeString,sizeof(TimeString),"%02d:%02d",GameMinutes,GameSeconds);
        TextDrawSetString(Textdraw0,TimeString);
    }
    if(GameSeconds == 0 && GameMinutes == 0)
    {
        OnGameModeExit();
    }
    return 1;
}

When I go ingame, all I see is 15:00 and they timer doesn't count down! Please help me!
