I want people to submit a survey, which has a unique, random number that is hidden to the end user. This number will be used as part of a "lottery" drawing, once all surveys have been submitted. The unique, random number will be sorted low to high, and the lowest 10 numbers will be winners. I envision my staff running a manual sort of the number in a web map, and then manually keying in a Selected = YES to the lowest 10 numbers. Any ideas how to do this? I know Global ID's are unique, but not necessarily random. I'm trying to make is as simple as possible for non-technical staff to run. I'd like to avoid ArcMap and ArcPro if possible - and do everything in ArcGIS Online, Survey123, web maps, etc.
How much more random can a Global ID get? You could look at a GUID field. I've used the procedure described here How To: Calculate unique identifier values similar to Global IDs but I couldn't tell you how to do that in Survey 123.
