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!

// Initializing the contract contract PeopleProfile { uint256 age;
struct Person { uint256 age; string name; }

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