I need to restrict access to a umbraco page , if website user logged in and have access to that perticuler page, in member area under the member type there is true/false property call accessToPageA so if customer logged in and accessToPageA=true then customer can see the page otherwise redirect to login page or subscribe request page

this is what i have tried but it gave error on save xslt.
