Question

我需要它做一个数学方程式，然后在“结果为：”下吐出答案当我按下按钮时，数字消失了，这意味着正在工作，但是没有答案。有人看到错误了吗？

<head>
<h1>Slugging Percentage Calculator</h1>
    <link rel= "stylesheet" href="thisisforlab7.css">
    <title>Lab 7</title>
      <script>
    function theCalculate(){
        atbat = document.getElementById("two").value;
        singles = document.getElementById("three").value;
        doubles = document.getElementById("four").value;
        triples = document.getElementById("five").value;
        hr = document.getElementById("six").value;
    document.getElementById("result").innerHTML = (singles + (2 * doubles) + (3 * triples) + (4 * hr) / atbat);
    } 
    </script>

<body>
<form>
    <h4>Batters Name: <input type= "text" name= "one"><br></h4>
    <h4>Enter Number of At Bats: <input type= "text" name= "two"/>  <br></h4>
    <h4>Enter Number of Singles: <input type= "text" name= "three"/><br></h4>
    <h4>Enter Number of Doubles: <input type= "text" name= "four"/><br></h4>
    <h4>Enter Number of Triples: <input type= "text" name= "five"/><br></h4>
    <h4>Enter Number of Home Runs: <input type= "text" name= "six"/> <br></h4>

    <button onclick= "theCalculate()"> What's the Slugging Percentage?</button>

    <h3> The Result is: </h3> <br>
    <span id= "result"></span>
    </form>


</body>

我已经编写了所有代码，但是按下按钮后我的按钮不起作用
