Retrieve data from a Button selection within a Lightbox to change states of multi-state boxes on Pages

This one is stumping me, and even the Wix team could only offer links to the openLightbox() API , and wix-storage API documentation with nothing specific.

I have a business with multiple locations. On an opening lightbox, a user will select a location. Let’s call them “Location1”, “Location2”, “Location3”, “Location4”.

The lightbox closes, and, depending on their selection, different information will show on several pages, including multi-state boxes.

How do I do this?! Once I get it once, I can just carry the same code across the pages and change accordingly, but it’s the initially passing data from the lightbox to a page that I’m struggling with.

Thanks in advance!
