Unfortunately, there do not seem to be many Plutus experts available in the forum. 
The only other recent thread about learning Plutus was more of a rant about the frustrating experience:
It seems that you started from a third-party example project. Have you tried starting from the tutorials in https://plutus.readthedocs.io/en/latest/ or https://developers.cardano.org/docs/smart-contracts/plutus/?
And an appeal: You are starting a lot of scattered threads with single questions (which unfotunately get very few answers). Can you try to consolidate your questions in a single thread? Perhaps this one?
