       <form id="form">
           <h1>Which is your favourite color</h1>
           Red<input type="checkbox" name="color1" value="red" id="color1">
           BLUE<input type="checkbox" name="color2" value=blue id="color2">
           Yellow<input type="checkbox" name="color3" value="yellow" id="color3">

					let form = document.getElementById('form')

let color1 = document.getElementById('color1')
let color2 = document.getElementById('color2')
let color3 = document.getElementById('color3')

let checkval = []

form.addEventListener('submit',(e) => {
    if (color1.checked){
    if (color2.checked){
    if (color3.checked){
    if(checkval.length > 0) {
        document.getElementById('message').innerHTML = checkval
