I have an Object in a DLL that contains other Objects.  These are all created by me.  

i.e.

  Type
     TMyObj = class (TObject)
       private
          FData: Integer;
       public
          construstor create;
          destructor destory;
          property MyInt read FData write FData;
 end;

   type
      TMyOtherObj = class(TObject);
         private
            FObj: TObj;
         public
            constructor create;
            destrustor destory;
             property MyData read FObj write FObj;
       end;

constructor TObj.create
begin
   inherited create;
end;

destructor TObj.destoryl
  inherited destroy;
end;

constructor TMyOtherObj.create
begin
   inherited create;
   FData.Create;
end;

destructor TMyOtherObj.destory;
begin
  FData.free
  inherited destroyl
end;

    When I try to add data to the FData var it does not work.

   What did I do wrong?

of course should be:
constructor TMyOtherObj.create
begin
   inherited create;
   FObj := TObj.Create;
end;
