这里是html内容

<div id="result-box" class="col-5">
                <h3 class="result" id="name" >Name: --- </h3>
                <h3 class="result" id="age">Age: ---</h3>
                <h3 class="result" id="class">Class: --- </h3>
                <h3 class="result" id="skill">Skill:--- </h3>
                <h3 class="result" id="gen">Gender: --- </h3>
                <h3 class="result" id="perform">Perfomance: --- </h3>
            </div>

这是js代码你告诉我这里面有什么错误

let name = document.getElementById('name').value;
let age = document.getElementById('age').value;
let class = document.getElementById('class').value;
let skil = document.getElementById('skill').value;
let gen = document.getElementById('gen').value;
let perform = document.getElementById('perform').value;

let name = document.getElementById('name').value
console.log(name)

在控制台面板中显示未定义，这背后的原因是什么，请指导
