Try the expression in this answer instead. It doesn't use a relation per se, but it matches features using a common field. | |

The list of spillway names that I can select from in the "Associated Spillway (sill) Feature" prompt is provided by a value relation widget in the form, with "Water Lines - Proposed" selected as the layer and "Name" selected as both the Key column and Value column. | |
