Change text when dropdown menu selection changes

In this prototype, I would like the numbers to change when I change the selection in the dropdown field. The dropdown selector has 5 options: All, Email, Onsite, Browser, SMS. The default selection is All. When I select an option other than All, I would like the numbers below to change.

Does anyone know how to do this?

The down and dirty was is to have a Selection Change event with cases on the dropdown. So you would have a case that says Selected Option of This equals option “All” and then chose set Text for the 4 labels. Then another else if case that says Selected Option of This equals option “Email” and then your Set Text for those 4 labels with the different values you want.
