New Post: Greška kod prijave pokretne trgovine

Nisam imao do sada slučaj prijave pokretne trgovine, a sada to trebam. Nakon čekiranja "Poslovni prostor nema adresu" u FISKI, na pokušaj prijave prostora program javlja grešku

System.NullReferenceException: Object reference not set to an instance of an object.
   at Fiskalizacija.DOS.SysTray.ConfigurationForm.btnPosalji_Click(Object sender, EventArgs e)
   at System.Windows.Forms.Control.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
   at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.ButtonBase.WndProc(Message& m)
   at System.Windows.Forms.Button.WndProc(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Zna li netko koji je uzrok tome, možda ja radim nešto krivo.
