Hello, I wanted to thank you for your great help you made it as solid and simple as can be! Although there is in the people.sol a minor mistake. So here is the code by correcting this minor mistake. Really grateful for your help! I wish you a beautiful week!

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

// Initializing the contract contract PeopleProfile { uint256 age;

struct Person { uint256 age; string name; }

Person[] public people;

mapping(string => uint256) public nameToAge;

function store(uint256 _age) public { age = _age; }

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

function addPerson(string memory _name, uint256 _age) public { people.push(Person(_age, _name)); nameToAge[_name] = _age; } }
