GetElementById Cannot Find Properties of null

Question

For some reason when I run this code, the console says cannot find properties of add event listener, but the names are correct.

Popup.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Popup</title>
</head>
<body>
    <h1>Shell Shockers Dark Mode</h1>
    <h2>Settings</h3>

        <script src="popup.js"></script>
        <input type="button" id="hide" value="Hide Name">
        <input type="button" id="show" value="Show Name">
</body>


<style>

    :root {
        --background: #00001D;
    }

    body {
        width: 250px;
        height: 500px;
    }

    h1,h2 {
        color: white;
        text-align: center;
    }

    html {
        background: var(--background);
    }

</style>

</html>

Popup.js



var hide = document.getElementById('hide');


hide.addEventListener('click', function(){
    localStorage['HideName'] = true;
})

var show = document.getElementById('show');

show.addEventListener('click', function(){
    localStorage['HideName'] = false;
})

My console here says that they cannot find the properties of null reading add event listener, but I double checked that the properties are correct? I can't seem to figure out why this is happening.
