Help needed with Pop Up! Settings

Please visit

I have pop up installed on that site, and client would like the non logged in site visitor to see the pop up no more than two times - what rules do I set in pop up to make that happen? Been trying out a few things and the box works, but it keeps showing up on every page instead of just 2 times and no more after that.

Screenshot of current settings attached.
