It's hard to tell unless you tell us your table structure/give a small snippet of data that replicates your problem. It looks like your comments table is being replicated in order to perform the join to the tbl_sales table, and so there are duplicates in the count.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
