專案(dpr)中有2個Form,一個Form如何取用另一個Form的變數?

假設：form2 有一個變數temp，要讓form1的buttom1按下後，form1的edit1顯示temp的值。    form2程式碼:     

unit Unit2;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs;    type
  TForm2 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    temp:String;
    { Public declarations }
  end;    var
  Form2: TForm2;    implementation    {$R *.dfm}    procedure TForm2.FormCreate(Sender: TObject);
begin
  temp := 'abcd';
end;    end.
 

------------------------- form1程式碼:

unit Unit1;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;    type
  TForm1 = class(TForm)
    Button1: TButton;
    Edit1: TEdit;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form1: TForm1;    implementation    uses Unit2;    {$R *.dfm}    procedure TForm1.Button1Click(Sender: TObject);
begin
  edit1.Text := form2.temp;
end;    end. 

我是頭號「問題」份子...

一時疏忽犯了錯誤,將temp變數放在{ Public declarations }這行之後造成 [Error] frmMainMess.pas(35): Field definition not allowed after methods or properties,感謝你的範例讓我找出錯誤
