session variables in repeated regions

[leeroy1]

I have a record set with record id in a repeating region on my page. It can show a max of 10 records at a time. When I click the "View Details" link I have in each repeated region I need it to open that specific record using a session variable. I've included the session variable in one of the repeated regions, but when I click on any of the events it always pulls the record id/session variable of the very last record instead of the one I've clicked on. Where exactly should I declare the session variable?
