Зачем вообще нужно создавать форму динамически, обычный способ не подходит:

Код:

unit Unit20;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

uses
  unit21;

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  Form1.Hide;
  Form2.Show;
end;

end.

Код:

unit Unit21;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm2 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form2: TForm2;

implementation

uses
  unit20;

{$R *.dfm}

procedure TForm2.Button1Click(Sender: TObject);
begin
  Form2.Hide;
  Form1.Show;
end;

end.
