Set the text content of the a tag to be the value stored in the variable inputValue.

It says am duplicating declaration inputValue

app.js 
let inputValue =linkName.value;
const    inputValue = document.getElementById('linkName').value;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>

You have two variable declarations using the name inputValue. a let and const. Since they are both in the same namespace, they are considered a duplication, which produces your error.

try changing one of their names, or simply not redeclaring the const.

let inputValue =linkName.value; // declared and initialized.
 inputValue = document.getElementById('linkName').value; // notice the removed const. In this way, you aren't duplicating the declaration, merely referencing it.

You have solved task 1 two different ways. Pick one and delete the other, then move on to task 2.

I recommend the 2nd one, it's more verbose but a more "good practice" solution.
