The two Screen Shots are not getting displayed under "Analyze the Results" section. Is anyone else facing the same problem?

From the author, many years too late, but still worth commenting on: Yes, indeed sharp readers, the aggregate clause in "Summarize the Data" shoud be "count(*)" and not "sum(*)"! I still do not know how I let that slip through! Many thanks to you for catching that and passing along. To all, I've enjoyed your comments and I especially appreciate those who have taken this a step beyond (or many more steps). That is precisely what I had hoped to accomplish with this article: to give folks a starting point that they could utilize in their own work. Now that we have SQL Server 2005, the included system views take care of a lot of this, but it is still useful for anyone who is still running SQL Server 2000.
