How do I Count the Number of Selections in a Multi Select List?

-Polak asked
Last Modified: 2015-03-08
I'm trying to use a combination of rules, default values, and the count() function to count how many selections a user makes from a multi select list populated from a SharePoint Data Connection. I've tried to follow this thread:

It's not working for me. I can only get the behavior to correctly count how many have been selected after one that was selected is DE-selected.

How do I accomplish this?
