How do I count the number of listed values for a field?

Question

I'd like to use automation to automatically update a field with the count of items selected within a multi-value list. I see that I can list the values with smart values, but how do I sum those into a count?

Welcome to the community.

I found a post from @Abby Kaske  that mentions something that might work.
