Why does deny roles not work in membership?

<location path="MoviesReview.aspx">
        <system.web>
            <authorization&开发者_如何转开发gt;
                <deny roles="Users"/>
            </authorization>
        </system.web>
    </location>

I am not able to restrict roles of users to this movies page.What could be the problem?

Oh It worked! I hadnt set the role for the users! It's proper now.
