Proyecto de Responsive Web Design

Hola buenos dias, me trabe en esta parte donde me dice: " * Debes tener un elemento input o button con un id de submit.

  • Falló:Tu #submit debe tener un type de submit."
    Si alguien me puede ayudar porque estoy re trabado y no me sale, muchas gracias.

Este es mi codigo:

<!DOCTYPE html>
<html lang="en">
<meta charset="UTF-8">
<link rel="stylesheet" href="styles.css">
<h1 id="title">Plataforma FreeCodeCamp</h1>
<p id="description">Gracias por usar nuestra plataforma</p>
<form id="survey-form" required>

<div><label id="email-label">Correo electronico<input id="email" type="email" placeholder="Correo electronico" required></label></div>
<div><label id="number-label">Edad(opcional)<input id="number" type="number" min="10" max="100" placeholder="Edad"></label></div>

<textarea id="submit" placeholder="Comenta aqui..."></textarea>
<input type="submit" value="Submit" id="submit">

The id should be unique, it should only be used on one element.

You have the id submit on two different elements. Only use it on the element you were asked to use it on.
