Combine several records into one

…would be transformed into this:
Any advice is much appreciated.


Create new empty table, link it to this table. Return here, and copy-paste primary field into new linked field here. Your empty table will be filled with the unique U1,U2… and links. Add “Elect…” field as lookup. Trasfer it to linked.
