I'm trying to simply display the selected user data in a certain format (using a Dynamic Entity Component).

Specifically, I want it to display as (CN="tuser1", FirstName="Test1", LastName="User1"):

"tuser1: User1, Test1"

I'm able to lookup the users fine, I can select one of the users fine, and it will display the attribute values that I add to the list of display expression attributes by default. 

But, I can't figure out how to add the 'colon', 'comma' and 'space' between the display attributes.

For example:

1. This Configuration in Form Builder:

[BLAH] Displays:

2. This Configuration in Form Builder:

[BAD] Displays:

3. This Configuration in the legacy PRD Flow:

[PERFECT] Displays:

Any ideas what I could be doing wrong or could do right instead?

Thanks!!
