What am I doing wrong here:

        <add name="UmbracoMembershipProvider" 
             type="Umbraco.Web.Security.Providers.MembersMembershipProvider, Umbraco" 
             minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="4" 
             useLegacyEncoding="true" enablePasswordRetrieval="false" 
             enablePasswordReset="true" requiresQuestionAndAnswer="false" defaultMemberTypeAlias="Customer" 
             passwordFormat="Hashed" 
             umbracoApprovePropertyTypeAlias="approved" umbracoLockPropertyTypeAlias="lockedOut" 
             umbracoCommentPropertyTypeAlias="comments" umbracoLastLoginPropertyTypeAlias="lastLogonDate" 
             umbracoPasswordRetrievalQuestionPropertyTypeAlias="passwordRetrievalQuestion" 
             umbracoPasswordRetrievalAnswerPropertyTypeAlias="passwordRetrievalAnswer" />

                    var member = ApplicationContext.Current.Services.MemberService.CreateMemberWithIdentity(email, email, email, "Customer");
                    ApplicationContext.Current.Services.MemberService.Save(member);
                    member = ApplicationContext.Current.Services.MemberService.GetById(member.Id);
                    member.PasswordQuestion = secretQuestion;
                    member.RawPasswordAnswerValue = secretAnswer;
                    member.IsApproved = false;
                    ApplicationContext.Current.Services.MemberService.AssignRole(member.Id, "Customers");
                    ApplicationContext.Current.Services.MemberService.Save(member);
