Hi karthik, this is what I noticed from the screenshot (red oval in attached image):

B.t.w. like Peter stated: post your definition, not just the screenshot (Rule 3)
Oh, and your attractor geometry component seems to be empty...

Hi.

I would advise you to fix your definition based on your tutorial.
1. You'd better change your initial input surface.(It's not a surface, but a Brep)
2. Both shift list components wrap value(input W) --> set to false
3. What is your rotation sources? ---> Input some points or curves as your rotation sources.
4. Don't flatten your angle input on rotate3d component (your tutorial indicates that you should change angle input from radian to angle degree)
5.Lastly, why don't you connect your final loft component to right in front of it?(flip matrix component)
