Apologies about the delayed response. It seems as though you have quite a few regions marked as "Identify" in your template. I would try to reduce the number of these regions initially, leaving around 2-3 of them. These regions would ideally be close to the edge and diagonal from each other, but in the event that you are unable to find suitable regions, I would recommend trying different region combinations to see what works. If at this point you are still unable to get the form to work, I would reduce the number of regions down to 1 or 0, and try again, slowly working up the number of these "Identify" regions back up to 2-3.
