I would like users to define the threshold they want to use on the field.  
When submitting the form definition to Central I don't get any error.  
But the form closes a soon as I start geopoint.  
[gps\_accuracy\_threshold.xlsx](https://forum.getodk.org/uploads/short-url/wEDEa4wcn81rUeFXh30Ow7nayX3.xlsx) (6.3 KB)

Is it a bug or is is simple not possible ?  
If it is not, I will add another geopoint question with another accuracyThreshold 😉

Hi @mathieubossaert  
`accuracyThreshold` was implemented to work with static values only. In your case it's a dynamic value that comes from another question.  
@LN have you ever considered making it work with dynamic values? Even if dynamic values are not supported there should be no crash.

thanks @Grzesiek2010 for your answer.  
For the moment I added 3 geopoint questions with 5,10 and 15 m threshold.  
Following the value that is set in user's prefs I hide the two other.

We've just released v2022.1.2 and now the crash should not take places in cases like that, just default values which is 5 meters for `accuracyThreshold` and 100 meters for `unacceptableAccuracyThreshold` should be used.
