How can I use the choose-when syntax inside the for-each loop?

I have an RTF template and want to display a single character or set of characters depending on which parameter they choose: It works perfectly outside the for-each:ROW loop, but if I insert it inside, the syntax doesn't work.

C

E

S

Do I need to use another form of syntax?  The P_CAMPUS is actually a parameter setup when the Concurrent Program runs and based on the 3 choices, it will display the letter associated with it.
