trying to get a random number on button click

I'm trying to use javascript to get a random number in the range of 0-20 to display in a text box after the user clicks a button, but I am so far unsuccessful. What is the error in my code?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="">

<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Untitled 1</title>
<form><input name="code" id="code" type="text" value="" >
<script type="text/javascript">
function makeid()
var randomnumber=Math.floor(Math.random() * 20)
<input type="button" style="font-size:9pt" value="Generate Code" onclick="document.getElementById('code').value = makeid()">

Answer Source

You function needs to return a value:

function makeid() {
    return Math.floor(Math.random() * 20)
