Xgen sliders

[John Cartwright]

Hello all,

I'm having a problem with xgen that is driving me to distraction (although xgen 
itself is really an incredible piece of software!).  Anyway the problem comes in
trying to use the slider object and retireve the value that is set.  As far as I
can tell from the documentation, the script listed below should work, but 
unfortuantely, the "accept" button causes the program to behave erratically and 
finally to crash with a segmentation fault.

The real issue for me is retrieving the value set by the slider and storing it 
in a shell variable for use in a command line argument and for later use in the 
xgen script.  Any help or suggestions would greatly appreciated.
