DeclarationError: Identifier not found or not unique.

Hey everyone!
I have zero experience in coding but i do have a good understanding of blockchain technology (Theory). I have been following the youtube video and i have come to a standstill at around 2:37:00 timestamp where i have typed the following code:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.8;

contract SimpleStorage {

    //this gets initialized to zero 
    uint256 public favoriteNumber;
    People public person = People({favoriteNumber: 2, name: "Bankole"});

    struct people {
        uint256 favoriteNumber;
        string name;
    }


    function store(uint256 _favoriteNumber) public {
        favoriteNumber = _favoriteNumber;
    }

    function retrieve() public view returns(uint256){
        return favoriteNumber;
    }

}

But I keep getting an error message when i try to compile:
DeclarationError: Identifier not found or not unique.
--> contracts/SimpleStorage.sol:8:5:
|
8 | People public person = People({favoriteNumber: 2, name: "Bankole"});
| ^^^^^^

Thanks for your help!

@bankyf You are creating struck with small letter of p that matches with people variable that's why it is giving duplicate error.

struct people {
    uint256 favoriteNumber;
    string name;
}

Change to this

struct People {
    uint256 favoriteNumber;
    string name;
}

OMG thanks!!!! God bless - I hope i am on the right path learning Blockchain dev since i have zero coding experience apart from a little SQL for Data analysis. I have heard from other sources that its better to learn HTML, CSS and JS first before delving into Solidity. Is this true?

@bankyf No, In my opinion, you should have at least basic knowledge of programming (it would be better for this course to have Javascript) and then you can continue this course, everything related to solidity, blockchain, smart contract, nfts, defi, etc all is there. You may feel some difficulty in frontend parts but these are just few. Once you finish the course and start building your own projects then go to frontend side and learn HTML, CSS, React, NextJs that why you will learn faster and will not distracted. If you do these all first you will definitely forget these until you finish this course. So keep in mind always learn technology while build something with that technology.
