Sorry to open this again, but I found that the proposed solution, that is perfectly working on Collect Desktop, has problems on Collect Mobile for Android. In fact, each time I enter and select a taxon name (and, therefore, the value of the calculated attribute is generated from the expression '`taxon_attribute_name/@familyScientificName`'), the app freezes with message "Collect Mobile has stopped unexpectedly", and it does not record neither the taxon attribute, nor the calculated attribute with the family name. This makes it impossible to use this method in the field. Is there any solution? Thank you again, Luca
