Thanks a lot, although this is not exactly as per the steps given in the book, it helped. Can you make videos of other examples given in the book!? As per given steps!?

in the book they use an older version so they need to use Harmonic ACT. In the newer versions, you don't need to use ACT and it will like the video.
