If you are talking about the Cash S&P500 Index which is calculated by the
CBOE, there is no volume provided on that symbol by the exchange.

Mark:

Point well taken.  Thanks.  I hadn't thought of that.  Would still like 
to make this work if for noting else to learn how to do it.  What I need 
is to be able to add volume to my S&P500 Index chart since my data 
provider (Quotes-Plus.com) doesn't provide it.
