Hello,
I am building a citizen science form that I need to spatial join the geopoint with a custom feature layer to assign a wildlife management unit, township, and county. I have it set up so the user only needs to put their personal information in once and then there is a repeat for each observation they encounter. For each observation, they need to identify a geopoint location. I then call that geopoint within the repeat and use JSON pull data to get the 3 attributes I'm interested in.
If I enter a single observation, everything functions as desired. However, if I enter two observations, the JSON query only works on the first observation and the second one returns "null".
Anyone know if the Java script I'm running isn't compatible with repeats? Thanks for any help!
