redirecting user

First, you need to use %%current_user_nicename%% instead. Then you need to check what Smith’s nicename is so as to ensure compatibility.

You also need to ensure that the box immediately below is set to Yes, always redirect ...

You haven’t said what user role you have given Smith. S/he will need an s2Member user role, not a standard WP role, as well as the custom capability.

If things still don’t work after checking all this, then I’d look for a plugin conflict.
