Thank You Pit.

I implemented this in minutes following your example.

The data is very well structured, unfortunately the data is not 
identical between suppliers.  Sometimes there are differences in prices 
or volumes fields.

So now I get unique records, but some have the same date.  Since I use 
the data as a time/price series, I can't have duplicate dates. 
Unfortunately I don't have time to work on this tonight, but will keep 
at it.

Thanks.
Snoopy
