The current method of editing a list item to enter this information is causing confusion. Suggested solution is to present the user with a form to fill out
While a big idea can be entered at the Gallery level, it is a different function. There can only be one overall Big Idea for the site/exhibition.
Need an Entry Form that can be edited instead of driving the user to the SharePoint List. Modify form/list so that only 1 Big Idea can be entered
