Select the <input> element with the ID linkName and store its value in the variable inputValue.

Not sure what is going on, I have selected the ID of the input element: document.getElementById("linkName");and placed its value: linkName, in the variable const inputValue = document.getElementById("linkName"); I have run the code outside of workspaces, and get no errors. I have previewed the code in workspace and everything looks good. My understanding is to use the document.getElementByID method to store the value of the input element (linkName) in a variable named inputValue. What am I missing?

const inputValue = document.getElementById("linkName");
<!DOCTYPE html>
        <title>DOM Manipulation</title>
    <link rel="stylesheet" href="style.css" />
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href=""></a>
        <script src="app.js"></script>

I should also add that I was able to successfully complete this code after a google search using :

let inputValue = document.querySelector('#linkName').value;

Why would the getElementByID not work? Thats what the code challenge task called for, right?

let inputValue = document.getElementByID('#linkName').value;

This works:

var inputValue = document.getElementById('linkName').value

The difference between that and the following you posted:

let inputValue = document.getElementByID('#linkName').value;

The d in Id is lowercase

No #
