Find Entries with Duplicated Field Value

    This script find duplicates in a chosen field and save results as a new list. It searches the datatree containing the script. This is the version with field chooser, so you specify on which field should be run the search after the script is run. There is also a minimalistic version where the field is specified directly in the script. You can find it in the dedicated forum topic.
