I am pulling data into a separate sheet (database) from a referenced sheet "Pipeline". In the Pipeline there are two columns, Index and Acronym. In the database I want these two column row data to JOIN together in a column named "Project Number" by recognising the same Index number in the Database and matching it to the Index number in the Pipeline, i.e. Pipeline column "Index" is 000001 and Pipeline column "Acronym" is ABC = auto-populates Database column "Project Number" with 000001 ABC. I've been playing with the below formulas but I am getting #INCORRECT ARGUMENT SET:
=MATCH(Index@row, Index@row, JOIN(COLLECT({Archive Index}, {Archive Acronym}, {Archive Index}, 1)))
OR
=JOIN(COLLECT({Archive Index}, {Archive Acronym}, MATCH(Index@row, Index@row, {Archive Index}, 1)))
