Hello, my name is Cesar. I’m currently migrating from ArcGIS Pro and Field Maps + Survey123 to QGIS and QField. I’m developing forms for field data collection, and I’m a beginner in form development. I have a problem trying to auto-fill one question based on another. The current_value function doesn’t work for me, so I’m using attribute($currentfeature, ...) instead. The issue is that the question I’m using to condition the second one (which is giving me trouble) is based on a nested table, and the function that works is returning the ID of the table, not its code. I appreciate any comments in advance. I’m new to this software, but I really like the freedom it offers.
my QGIS version is 3.40.8
Cesar,
Glad to have you in the community! You are diving a bit beyond my expertise, but I did spot this blog post, https://woostuff.wordpress.com/2011/09/05/qgis-tips-custom-feature-forms-with-python-logic/ , which might give you some tips.

You may want to take a look at Value Relation in the Attributes Form part of QGIS. You can set that up with your data and it should transfer over to QField.
