how to create a report that shows the average of a data point

Hi all,

I'm a backend developer (new to omniture)working with our front end guys to implement some analytic reports.

Got a few questions, hope someone can shed some lights on them.

#1.  our report needs to track what is the average number of times the users open a certain css modal during the logged in session.  How should I create the report (more specifically, what kind of report should it be?  custom traffic?)

what we've done so far:

We've added  _satellite.track('InboxOpened') to our front end open-modal logic  and it's firing the call with these params:

I've already setup these data elements on the dtm side:

eVar14="%inbox.open.count%"

prop14=eVar14

event27

question #2 (unrelated to #1). In the default page view report, it is not showing any page view count, it's always zero.  any idea?  I've setup a page load rule in dtm, when the test JSP finishes loading, I see the tracking call firing, with these params, but report shows zero.  I'm sure it's hitting the right site (staging)
