Count unique contributors in 2 columns

Alex B

Hi,

I am trying to count the number of unique contributors to a project.

Our structure requires us to use 2 contact list columns, with only one entry per row (no multiple contacts in a cell)

The 2 columns are Assigned To, and Collaborator. They are several columns apart.

In some instances the lead on one aspect (Assigned To) may be a Collaborator on another part of the project

I am trying to count the TOTAL number of UNIQUE project team members.

I can easily use COUNT and DISTINCT to get one column individually - but cannot seem to be able to manage 2.

Help?

For context - the outcome I would want is a count of 3 based on the view above. There are 3 total unique contributors in this view.

I would suggest hidden helper columns that are next to each other with basic cell references set as column formulas. Then you can select the double column range in your COUNT/DISTINCT.
