Adding Dialog popup to Tab in Tabbed Application

[Me]

I am using VC++ VS2012
I have a Tabbed Dialog application with two tabs
I am trying to add a popup dialog window for one of the tabs
I create a new dialog IDD_DLGLIST and a new CDialog class for it
Dlglist.cpp using the Class Wizard
When I click Finish & Apply in the Class Wizard the new Dlglist.h come up
in editor.

class Dlglist : public CDialog
{
DECLARE_DYNAMIC(Dlglist)

public:
Dlglist(CWnd* pParent = NULL); // standard constructor
virtual ~Dlglist();

// Dialog Data
enum { IDD = IDD_DLGLIST };

protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support

DECLARE_MESSAGE_MAP()
};

The line "enum { IDD = IDD_DLGLIST }; has the IDD_DLGLIST underlined in red
Error: identifier "IDD_DLGLIST" is undefined
When I try to build the same error comes up?
I see IDD_DLGLIST in the Resource View?

What is wrong?
TIA
