I have in QGIS 3.28.8 two point layers: source_p and target_p I want in source_p layer to create a dropdown to "TargetFID" field with Value Relation to target_p layer with only 3 nearest points matches on target_p layer. Value relation should activate when I select a singel point at source_p layer ... current_value selected I tried to filter expression, but something is wrong?

current_value(overlay_nearest(layer:='target_p', expression:="fid", limit:=3, max_distance:=15000))
