Pop-up not working

Hi-

Newbie here. Very limited understanding of coding…

If you click on the question mark icon on the right, you can see a popup I made that works fine.

If you click on “Open popup” a row down on the left, that’s supposed to launch a different pop-up, nothing happens. None of the other popups I’ve made work either. I’ve tried tweaking the Z index settings, but it hasn’t fixed the problem. Can you help? Thanks.
