You don't use the good callback, look this code :

Code:

public OnPlayerClickPlayerTextDraw(playerid, PlayerText:playertextid)
{
	if(_:playertextid != INVALID_TEXT_DRAW)
	{
		if(playertextid == GUI_HuongDan[playerid][1]) // line 1213
		{
			PlayerTextDrawShow(playerid, GUI_HuongDan[playerid][10]);
		}
		else if(playertextid == GUI_HuongDan[playerid][2])
		{
			PlayerTextDrawShow(playerid, GUI_HuongDan[playerid][6]);
		}
		else if(playertextid == GUI_HuongDan[playerid][3])
		{
			PlayerTextDrawShow(playerid, GUI_HuongDan[playerid][9]);
		}
		else if(playertextid == GUI_HuongDan[playerid][5])
		{
			PlayerTextDrawShow(playerid, GUI_HuongDan[playerid][11]);
		}
		else if(playertextid == GUI_HuongDan[playerid][13])
		{
			for(new i = 0; i < 23; i++)
			{
				PlayerTextDrawDestroy(playerid, GUI_HuongDan[playerid][i]);
			}
		}
	}
}
