This is for SSRS 2005.

It's so weird. After I added GroupName in my stored procedure SQL
statement like this that my SSRS dataset runs:


SELECT *, GroupName = 'Arizona' FROM mytable


Then I added GroupName to my Chart, I started to get that. Even if I
delete that from my chart, I still get it. I guess because it's still
in my dataset, it doesn't like it but why? All I did was add that
GroupName as an extra field to my query for the dataset to bring in..I
don't get why it doesn't like it.
