Migration to .NET 2003 : Help Me !!!

Hello Gurus,
I am trying to migrate my VC++ 6.0 application to Visual C++ .NET 2003. But I am getting some errors related to ON_COMMAND_RANGE message map.

I have following code:

ON_COMMAND_RANGE(IDC_STEP1_RADIO21, IDC_STEP1_RADIO25, OnStep2)

ERROR-->
g:\NET30JULY\LanguageInterpretation\QuantitySelectionDlg.cpp(135): error C2440: 'static_cast' : cannot convert from 'void (__thiscall CQuantitySelectionDlg::* )(void)' to 'void (__thiscall CCmdTarget::* )(UINT)'

All errors are related to same message map from different files. I think ON_COMMAND_RANGE is deprecated MFC 7.0. Could you please help me with this ??

Thanks in Advance !!!!

Have you forgotten to define the OnStep2 method defined with the UINT parameter required for ON_COMMAND_RANGE?
