Column Type for Range Between 2 Numbers

Ok, I’m getting an error message now in a number of columns, which has rendered Bob’s solution useless now. It was working perfectly this weekend, so I’m thinking it has something to do with Glide, and not the way they’ve been set up. Here’s the screenshot below. When I click on Reload, nothing happens. When I click on Learn More, the page won’t open, but it points to this → https://www.glideapps.com/docs/experimental-code-column.

Any idea what might be going on here?
