Using Replacement Strings in rubrics

Adam.Woodrow22

Has anybody had success using Replacement Strings in rubrics?

 

I want to address the student in the feedback section for the criterion, however, the {FirstName} string defaults to my name.

 

For example, Abbie Student should see: "Hi, Abbie. Good job."

 

Instead, Abbie Student sees: "Hi, Adam. Good job."

 

Any ideas?
