[交流] 【求助】delphi运行一个书本程序，运行不起来

我建立了两个FORM，把他们放在一个工程内部，但是运行出现错误，其中unit1.pas的源代码是：
CODE:
unit Unit1;

interface

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

type
  TformInfoInput = class(TForm)
    科员: TComboBox;
    男: TComboBox;
    行政部: TComboBox;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    Label1: TLabel;
    Label2: TLabel;
    Label3: TLabel;
    Edit1: TEdit;
    Edit2: TEdit;
    Edit3: TEdit;
    Label4: TLabel;
    Label5: TLabel;
    Label6: TLabel;
    Label7: TLabel;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  formInfoInput: TformInfoInput;

implementation

uses Unit2;

{$R *.dfm}

procedure TFormInfoInput.btnShowClick(Sender: TObject);
begin
   formInfoShow.ShowModal;
end;
procedure TFormInfoInput.btnClearClick(Sender: TObject);
begin
  EdtName.Text='';
  EdtAge.Text='';
  EdtPhone.Text='';
end;
procedure TFormInfoInput.btnExitClick(Sender: TObject);
begin
  formInfoInput.Close;
end;
end.

unit2的源代码是：
CODE:
unit Unit2;

interface

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

type
  TformInfoShow = class(TForm)
    Button1: TButton;
    Label1: TLabel;
    procedure FormShow(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  formInfoShow: TformInfoShow;

implementation

uses Unit1;

{$R *.dfm}

procedure TformInfoShow.FormShow(Sender: TObject);
var
tmpstring:string;
begin
  MemShowInfo.lines.Clear;
  tmpstring:='姓名:';
  tmpstring:=tmpstring+formInfoInput.EdtName.Text;
  tmpstring:=tmpstring+#13+#10;
  tmpstring:=tmpstring+'年龄:'+formInfoInput.EdtAge.Text+#13+#10;
  tmpstring:=tmpstring+'性别:'+formInfoInput.cmbxSex.Text+#13+#10;
  tmpstring:=tmpstring+'职务:'+formInfoInput.cmbxDuty.Text+#13+#10;
  tmpstring:=tmpstring+'电话:'+formInfoInput.EdtPhone.Text+#13+#10;
  tmpstring:=tmpstring+'部门:'+formInfoInput.cmbxWkSpace.Text+#13+#10;
  MemShowInfo.Lines.Add(tmpstring);
end;
procedure TformInfoShow.btnQuitClick(Sender:TObject);
begin
  formInfoShow.Close;
end;
end.

但是编译工程会出现错误：

出现了很多为声明的变量，如： E2003 Undeclared identifier: 'MemShowInfo'，Undeclared identifier: 'formInfoInput'等；tmpstring:=tmpstring+'年龄:'+formInfoInput.EdtAge.Text+#13+#10;这句的EdtAge.Text好像不能直接访问吧
