reciepient of message - requested end

[Stephan HŽning]

Hi all,
 
i have a problem with the requested end in an activity step. For the most
of you is this problem maybe too simple. But i=B4m the only one in our
company who build wf and i am new in this area. So i have no one else to
ask.
 
I built an activity step with a requested end (not modeled). The
reciepient is an user. Now i will give him a note who is the actual agent
of the activity step of this workitem. I tried several expressions. But
never saw the actual agent.
Can someone of you help me?
 
I know that some of you are laughing about my problem.
 
Cheers
Stephan
