hi all was hoping for some help if possible. i have built a survey that has the ability to capture points, lines and polygons. It gets published ok but when i fill out the survey keep getting a "operation roll back" error. Have read lots of the posts and have tried many of the suggestions though still cannot get it to work. I assume that there is something "simple" i am not doing - any help or guidance would be greatly appreciated . I have attached the XLS Form for context
