DeclarationError: Undeclared identifier. "..." is not visible at this point - ethereum

Question

I am practising this tutorial in Remix IDE - https://www.youtube.com/watch?v=_aXumgdpnPU
I saw in the Chainlink documentation that their Randomness VRF code has been changed since the development of the video.
I started replacing the parts and trying to deploy the class via Remix but it gives an error which I am not sure how to fix.
Would you be able to check what I have as code and I'll send a screenshot of the error?
