Why can't I retrieve this POE session's options?

[Tim Klein]

I expected the following short program to print "My name is Tim" 
followed by "My name is Mud".  Instead, this is the output:

My name is
Use of uninitialized value in concatenation (.) or string at opt.pl line 25.
My name is Mud
Apparently, the 'MyName' option isn't getting registered properly 
during the creation of the session.  But when I later set the same 
option using the option() command, it works fine.

Can someone spot what I'm doing wrong, most likely in my create() 
call?  It's probably something stupid, but I just can't see it. 
Thanks for any help!
