Grouping Dates-Pivot Table

I was following a pivot table introductory page and I found the way how to group/ungroup dates. It is demonstrated on the page that how you can group your dates using Pivot Table and display it "vertically". The problem is though I tried it out but couldn't present my dates in "vertical" way. Please Find attached file "Excel Query-01" where I used Pivot Table to Group dates vertically (couldn't succeeded though).
The second sheet "Dates presented vertically" contains the actual way shown on webpage to group dates vertically. Please let me know where I go wrong? Thanks

your dates are separate fields in the source data so you can't group them

I said in the source data. in the web page the source data must be one date field

you need three columns-Product, Date and Value-in your source data
