I was wondering if you all might be able to help me out.  And point
out what in the world I am doing wrong.  I have worked on this for
hours and haven't been able to figure this out.  I would appreciate it
if someone could possibly send me (e-mail) a corrected copy of this code.
Thanks.  And much appreciation.  :-)

Bryan.
