How to let my ini file determine whether to show a splash screen?

Hi Wizards!

I want the user to be able to control whether a splashscreen is shown or not. THis shoudl be done by means of a checkbox in the application in conjunction with an inifile. Now this is what I have >

//code

private
    FShowSplash: Boolean;
    property ShowSplash: Boolean read FShowSplash write FShowSplash;
......

procedure TForm1.FormCreate(Sender: TObject);
var
  Ini: TIniFile;
begin
  Ini := TIniFile.Create( ChangeFileExt( Application.ExeName, '.INI' ) );
  try if
  Ini.ReadBool('GUI','ShowSplash', False) then
  ShowSplash := False else
  ShowSplash := True;
  finally
    TIniFile.Free;
end;
end;

.....

procedure TForm1.FormShow(Sender: TObject);
begin
if ShowSplash then
    Sleep(1000);
  fSplash.Release;
end;

// end of code

Delphi's complaint:[Error] Main.pas(61): This form of method call only allowed for class methods. Now my guess would be that I'm doing something terribly wrong so my question is what am I doing wrong here?

Any other approaches are welcome as well ofcourse, as long as teh user is able to control whether the splash screen pops up or not.
