I'm working on a formula to return an account number if the criteria matches for Client AND Service Description. For example, if a user selects Medical Education from a Service Description dropdown list when creating a work order for Client X, the corresponding Medical Education account number for Client X should be returned.
I tried the Index Collect formula below but got an Incorrect Argument error.
=INDEX(COLLECT({IO Number}, {Client}, [Client Name]@row, {Service Description}, [Service Description]@row, 1))
Am I on the right track or is there another combination that I could use?
Thank you!
