Trouble with Pmw ComboBox get()

[Cindy Huyser]

I have a form on which I am using several combo boxes to get
information.  I
  have been using the info to build a tuple to pass to a function, and
it's been
  working well.  Now, suddenly, all I get from the get() function are
the
  default selected values; I'm beginning to suspect I have a mean hidden
  character somewhere. 

  Any ideas?  The code declaring the boxes and then getting info from
them is
  pasted below.
