Default geopoint using select_one and calculate

Hi @seewhy , I hope you're fine.

You should check this discussion and solution :

Get custom data from choices sheet for calculation

You can see an example of this kind of querying in the docs section on dynamic defaults from form data. Look at the example in "XLSForm that looks up default values based on a selection" where we show using a choice_filter of true() to force the creation of a secondary instance. That is equivalent to not having a filter at all because all values are included. That's what I would recommend for now.

I faced the same "problem" (I wanted to show water level values for a given station at a given time) and solved it thanks to @LN and @Grzesiek2010

Next week I have to improve the form and I also will show the place of the monitored / selected station.
