Here's the pot files I use.
Put the .lib file in the sub folder, and the .asy file in the sym folder.
Or perhaps you can use them to determine the error in your files.

How to use the pot in LTspice?

I am unable to proceed from here

Welcome to AAC!
Rtot is the full end-to-end resistance of the pot. Wiper is a value in the range 0 to 1 and is the fraction of that resistance between the wiper and the 0% end. You can right-click the symbol and edit either parameter. You can also declare wiper as a parameter and step its value during the simulation.
