profiles in Sitecore DMS 2.0

Question

I'm just getting started on Sitecore DMS 2.0, and not sure if I understand how the profiles work.

I'm trying to have a page that will show different info depending on if you're just a regular visitor or belong to a specified profile.

I've created a persona, Marketing person, with a maximum score of 10. I've then created a few pages that gives different scores (3, 4, and 4) to the Marketing persona if you view them. I thought that these were cumulative, i.e. if you viewed all three pages your total score for the Marketing persona would be 10, and if you then view the page with the profile dependent content you would see the content for that profile. However, it seems like it's only keeping the score for the last page. What am I doing wrong?

UPDATE: My condition is: In the rule set editor under Profiles and Patterns I've chosen "where the value of Marketing person profile key is greater than or equal to 10".

Thanks,

Annelie
