Lesson 1: Cannot add new data to mapping

[kailashchoudhary11]

Why doesn't the addTest function add a new object to the mapping?
The add function is working as expected.

mapping(string => uint256) public nameToAge;

function add(string memory _name, uint256 _age) public {
    nameToAge[_name] = _age;
}

function addTest(uint256 _age, string memory _name) public {
    nameToAge[_name] = _age;
}

@kailashchoudhary11 It is working fine.
