Simple level system with xp, money, and levels
<p>I am trying to create a simple level system, but it somehow doesn't update the levels. Can anyone help me with this? (The money and xp works)</p>

<pre><code>var money = 0;
var xp = 0;
var level = 1;

window.onload = function() {
 document.getElementById("money").innerHTML = 'Money: ' + money;
 document.getElementById("xp").innerHTML = 'XP: ' + xp;
 document.getElementById("level").innerHTML = 'Current level: ' + level;
}

function giveExp(number){
 money = parseInt(money) + 50;
 xp = xp + 100;

 document.getElementById("money").innerHTML = 'Money: ' + money;
 document.getElementById("xp").innerHTML = 'XP: ' + xp;
}


if (xp &gt; 150 &amp;&amp; xp &lt; 450) {
 level = level + 1;
 document.getElementById("level").innerHTML = 'Current level: ' + level;
}
</code></pre>
