Thanks flowdy was the explanation. I agree with you, I wouldn't use this in a production code. I was just trying to understand how nesting can be done. I am of the type who would learn more by looking at a solution then reading through the doc. Your solution has shown me a clear way of nesting maps and I appreciate your help for that. :)
