thanks for all your replies, i have modified my application.cfc with the code snippet sent
<cfcomponent> <!--- You don't actually have to use the "this" scope, but most Application.cfc examples do. ---> <cfset this.name = "myappname"> <cfset this.sessionmanagement = "yes"> </cfcomponent> and it has fixed the previous error but now i am back to the original error of session not valid when i try to use the session variables in my pages as follows: <cfscript> session.student = StructNew(); session.student.name = "fred"; </cfscript> the application.cfc is in my root folder and the page trying to use the session variables is in a sub folder. the session variables are also enabled on the cf admin this is prob something so simple - but then its always the simple mistakes that take longer to fix! thanks again for all your help ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:254177 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
