I've already searched for my problem, but the solutions were not able to help me.
Here's the code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Der Einmaleins - Trainer</title>
<link href = "style.css" type = "text/css" rel = "stylesheet">
</head>
<body>
<h1>Der Einmaleins - Trainer</h1>
<button type="button" onclick = "start();">Start</button>
<button type = "button" onclick = "fertig();">Fertig!</button>
<input id = "erginput" type = "number" >
<br>
<label id = "rn1"></label>
<label id = "multiplication"><label>
<label id = "rn2"></label>
<script>
function start()
{
//var anzahl = 0
//while (anzahl < 20){
var randomnumber1 = getrn();
var randomnumber2 = getrn();
document.getElementById("rn1").innerHTML = randomnumber1;
document.getElementById("multiplication").innerHTML = "x";
document.getElementById("rn2").innerHTML = randomnumber2;
//}
}
function getrn(){
var min = 3;
var max = 10;
var randomnumber = Math.floor(Math.random() * (max - min)) + min;
return randomnumber;
}</script>
</body>
I thought that the null is because randomnumber2 oder rn2 is not defined since I saw that mistake in other codes, but here they're both defined, aren't they?
Thanks in advance!

You had invalid markup! </label>
was not closed..
function start() { var randomnumber1 = getrn(); var randomnumber2 = getrn(); document.getElementById("rn1").innerHTML = randomnumber1; document.getElementById("multiplication").innerHTML = "x"; document.getElementById("rn2").innerHTML = randomnumber2; } function getrn() { var min = 3; var max = 10; var randomnumber = Math.floor(Math.random() * (max - min)) + min; return randomnumber; }
