I'm trying to get a value from a layer's query results. The field to-be-read should be retrieved from a value. Is it possible to do something like this expression and how should it be formatted? Thanks in advance!

=$query1.features[0].attributes.$valueQueryField.results

  Yes!  Use brackets to signify a computed property, i.e.

  =$query1.features[0].attributes[$valueQueryField.results]

  You can daisy chain this syntax by the way.

  =$query.features[$forEachFeature.pass].attributes[$valueQueryField.results][$valueSubproperty.results]

  Ah, thanks a lot. I tried various formats with no result, but this format works great!
