Looking for help with Reports

So far the only thing that does not seem to be very intuitve with Netvault is building reports.  Hopefully this will be made simpler in future releases.

Anyway, we rotate some of our tapes on a 14 day schedule.  I would like to generate a report that shows all tape written between 10 and 14 days before the current date (or between X and Y number of days).

I've created a report that shows tapes that were written 14 days (or X days) before the current date but that gives me all the tapes every written longer ago than 14 days.  I need to narrow it to a window of days.

I would also like to be able to generate a report based on the "Offisite Location" field.  Like, all tapes that have an "Offsite Location" that begins with "Safe."

Any thoughts/help will be greatly appreciated.

Thanks, Tad
