Popup keeps coming up after we clear it on boxilla

Hi! I got my popup working perfectly! My only question is where in the set can I change the settings that once someone X’s the box, it doesn’t keep showing up on every page of your browsing experience.

So now if someone arrives at my home page, X’s out of the subscribe pop up and then reads an article 5 seconds later, it pops up again on the blog post again.

is there a way to tell boxilla that once someone x’s the box, don’t prompt it again while their browser is open on this page? Thanks so much!
