Multiple Logical Operators in javascript
<p>I want to check the following</p>

<p>1: Is x a number<br>
2. If x is less that 5 or greater than 15, sound alert
3. If all is ok, callMe() </p>

<pre><code>var x = 10;
if (isNaN(x) &amp;&amp; ((x &lt; 5) || (x &gt; 15))) {
alert('not allowed')
}
else
{
callMe();
}
</code></pre>

<p>What am I doing wrong?</p>
