Hi @vidarv,
If you want to show all records and their selected items for QualitativeTargets, my first comment will have the solution you seek. The Items property of the gallery will be ActivityPlan ,which will show all records in that SharePoint list.
To show all values of a Multi Selection choice field (meaning multiple values can be stored), you will need to add a combobox in that gallery with Choices(LISTNAME.QualitativeTargets) as the Items property and ThisItem.QualitativeTargets as the DefaultSelectedItems property.
If you want to display the values concatenated in a text field instead of a ComboBox you will need to add the following code to the Text property of the label:
//This will show the text as Value1, Value2, Value3
Concat(ThisItem.QualitativeTargets, Value, ", ")
If this solves your question, would you be so kind as to accept it as a solution.
Thanks!
