I was able to edit the dashboard a minute ago. Then I went else where in the Model to view. When I came back to the Dashboard, I was not able to edit. No changes were done in the Dashboard. I tried another Model and encountered the same problem...i.e. all of a sudden, I could not edit Dashboard.
Did you make any changes in the page selectors? I mean you need to be at the lowest levels of hierarchy on the dashboard to input any number- unless you are using breakbacks. Check and let us know if that is not the case
