How to Save the Field Value of the Current User's Location to Another Field?

I have a problem that I have not been able to solve for a month. If you are a master, I would appreciate if you could give me the solution to the problem below.

The setup I want is as follows.

when a user is comes within the radius of a destination address of data type “place”, the value of the “point_stone_power” field of that destination (data type : number) is stored in the “point_stone” field of data type “User”.

However, the value of “point_stone_power” field of the first registered destination (first item), which is not where the user is, is stored in the “point_stone” field of the User data type.

The GPS Tracker is working every 6 seconds and is tracking the user’s movements accurately.

So the problem seems to be due to incorrect syntax below.


search for place:filtered (Advanced: This place’s Address distance from Current geographic position < this palace’s Radius(km)) :first item’s Point_stone power.

I think the syntax “This place’s Address distance from Current geographic position < this palace’s Radius(km)” is not being recognized because the first item value of all destinations is being stored.

Or, is an additional action necessary in the place to check the user’s current location? I wonder if a custom state should be set to store the user’s location.

P.S.: Some people also advise that even if the GPS Tracker is working, the bubble cannot detect in real-time whether the user has entered the radius on its own, so you should use CUSTOM STATE to store the address that the user has entered the radius. Do I really need to use custom state to arbitrarily save the address the user entered?
