I am trying to make a field that gives unique sample ID's if plant samples are indeed collected by individual collectors/surveyors. Something like
{Year}{created_user}{last number +1} would be terrific. But even a plain old autoincrementing integer would be better than nothing. Is this possible?
I am using ArcGIS 10.2.2, ArcGIS online, and version 10.2.7 of the iOS Collector app.
Thanks!
