Can someone help me to find an error in my code

The _name parameter in the addPerson function needs to have the keyword "memory" in front of it.
So it turns into:

    function addPerson(string memory _name, uint256 _favNum) public {
        people.push(People(_favNum, _name));
        nameToFavoriteNumber[_name] = _favNum;
    }
