Subject: Command Line Arguments problem

Greetings,
  I am working on a project and I added command line options.  Today, I
took the fateful step in adding the capability to do multiple options in
the program.  For some reason, the code, which worked perfectly before
this, now spews out the error:
    undefined method "-" for nil:NilClass (NoMethodError)
The code in question is:
    dateArr[0] = DateTime.parse(ARGV[1])
Now, this error pops up because ARGV[1] is nil.  But if I run the
program :
    ruby Hercules.rb -c 2010-04-15
ARGV[1] should be 2010-04-15.  What is the problem here?

Thank you,
  dlucci
