If condition checking for two TextFields Value
<pre><code>if(a.value === undefined || a.value.length&gt;37 || 
        b.value === undefined || b.value.length &gt; 256) {
</code></pre>

<p>If the first one is undefined or greater than a length of 37. I get a error, but it does not check for the second field at all. </p>
