Hello Sherri, strange, so there is a difference with my tested situation. This is what I did:
- I work in Kentico v8.2 (but I don't think that is the problem)
- Added an field with the name : CADate
- Data Type : Boolean
- Added an field with the name : CA2
- Data Type : Boolean and Form control : Radio buttons
- Options : List of options and the options are:
true;True
false;False
- In my email notification I use an custom layout and added in the source this macro : {% CADate == null ? "" : (CA2 ? "CA" : "CS") %}
And this works for me, so hopefully you can now see what is the difference with your configuration. Good luck!
