@pohrerhub That python console error is referring to a collection that may have been deleted. There is a variable named `widget_collection` that is being assigned to the first parent collection of the widget. That parent collection was either cleared or has been deleted. If you send me the file I can probably help you troubleshoot it. I haven’t gotten to that point in the course but check your collections and collection parenting for the widgets. I hope that makes sense.
