Clients in multiple categories

Hi all,

I have a problem that I'm not sure how to even start with so hoping someone out there can give me a hand. I have a table that listes all our customers and the number of times they have received task they have received. These tasks are linked to another table called "Service Types" that categories all the tasks into a list of 20 different service types. I have a visual which shows the customer name and shows the distinct count of whether or not they have received a task under each service type:

What I'm trying to achieve is instead of the distinct count in the total (showing 1 client) is a count of how many service types they have used and then filter the table to only show clients who have accesses more than one service.

At the moment I'm going round in circles trying to work out how to achieve this. Any help would be appreciated. Thanks, Emma
