Hello. I am new to all programming, and taking some basics course atm.

So here is the problem that I have now:

When the user click the button, it should print the sum of all the boxes.
I am not sure what I've done wrong with this code and a little help would be appreciated!

<!DOCTYPE html>
<meta charset="UTF-8"/>
<title>Ostorkori 🛒</title>
Tuote 1: <input id="tuote_1"/>
Tuote 2: <input id="tuote_2"/>
Tuote 3: <input id="tuote_3"/>
Tuote 4: <input id="tuote_4"/>
Tuote 5: <input id="tuote_5"/>
Tuote 6: <input id="tuote_6"/>
<button type="button" onclick="hintaYht();">Yhteensä</button>
<div id="tulosX">

function hintaYht(){
var tuote1 = Number(document.getElementById(tuote_1).value);
var tuote2 = Number(document.getElementById(tuote_2).value);
var tuote3 = Number(document.getElementById(tuote_3).value);
var tuote4 = Number(document.getElementById(tuote_4).value);
var tuote5 = Number(document.getElementById(tuote_5).value);
var tuote6 = Number(document.getElementById(tuote_6).value);

var tulos = tuote1 + tuote2 + tuote3 + tuote4 + tuote5 + tuote6;
var x = document.createElement("tulos");
var t = document.createTextNode("This is a span element.");

document.getElementById("tulosX").innerHTML = tulos;

The ID value must be quoted:

(unless it's a variable, but that's not the case here).
