Counting how many employees worked on multiple customers

[dbenson]

Newbie here!  This seems like an easy question, but I'm having a hard time figuring out the proper formula here.  

I have a database with employee names, customers they worked on and how much we paid them to work on each of those customers.  I'm trying to do a simple analysis to see the names of my employees that worked on more than one customer (and to see which exact customers they are working on).  

I believe the best way to represent this is a matrix table and I was running a basic Distinctcount on the employees to show the boolean values on whether they worked on a customer or not.  That part is fine.  However, I cannot get the sum at the end to see if they did in fact do more than one customer as the grand total will default to 1 for all employees as the Distinctcount looks to  be re-running for the filter context. The below table is what I am currently seeing.  Any advice here?  

	Customer A	Customer B	Customer C	Total
Employee A	1	1		1
Employee B	1		1	1
Employee C		1		1
Employee D			1	1
