Please check the video in this post Test#4 where I used only two columns and the result came out is incorrect. Basic filter is working but the results are not correct. How do we know that the result shown are correct. I could Identified only cause I also maintain them in Excel and by doing some manual calculations. Working ka problem nahi hai kuch na kuch result to aahi raha hai but kya wo sahi hai 100% if yes how to cross verify?
