Hi Don.

No, the browser back button is not used. All I do is to first create a session. Then I assign my SAVE_ variables, build a link to the next sas program and publish it all on a web pages. So far all good. But when I click on the link the SAVE_ variables change so when they are displayed on the next page they have taken on the values of the next hierarchy levels!
