Edit: problem solved.
Knowing that I didn’t want the element visible on the page, I unchecked ‘This element is visible in page load’. Apparently this also disables functionality of the element. After I checked the box, the list was populated. The element is invisible anyway.
The List of Numbers looks straightforward enough, but I’m not getting what I expect.
In short, requesting a list that starts with 1, incremented by 1 and 12 in length, I am getting an empty list.
Here’s how I specified the list:
The result is empty.
What am I missing? Is there some documentation I should have found that explains what I should be doing?
