The end result was too simple. But I took a lot of time trying to figure out what needs to be done. I think one of the traps is to think that every problem has a complex solution. Sometimes the solution is as simple as they come.

I'm not sure what I did is bulletproof, but I matched the output!

My solution is attached - I like the simplicity of many of the other solutions

I really liked the way others used the summarize tool to make the workflow simpler - very elegant indeed.
