Well, of course, I should have thought to set it to 0 instead of writing unpublished. Thank you. I have it working now from using the "process" button. Even though I had it set to trigger every minute, I had to manually process the mass action. Is that normal?
Also, with the trigger selection, there is an option to choose every minutes, days, weeks, or months but not a field to set the number of minutes, days, weeks, or months. The selection being plural, e.g. days, makes me think there should be a trigger that I could set to occur every X number of days. Am I missing something here?
