[CM] adding cmn 'text' through cm process

[bill sack]

hello,
i'm experimenting with adding cmn text arguments through a cmn process, 
but haven't gotten very far. something like this:

             for f = (string 'hey)
             output (new cmn :time (now)
                         :duration r
                         :note n
                         :staff stf
                         :data `(text ,f))

produces an error:

Error in function CMN-EVAL:  TEXT is not a cmn variable.
   [Condition of type SIMPLE-ERROR]

i've tried some other variations but all have more or less the same 
problem. i'm just trying to add a few more arguments to a note object. 
what would be the correct way to do this?
