how to join the value of 3 variables and add them to a hidden field
<p>I have 3 variables and I was wondering how to join their values and add them to a hidden field,</p>

<pre><code>   document.getElementById('my-item-name').value = meat.join("\t");
</code></pre>

<p>it works for 1 but when I add the other variable it doesn't work.</p>

<pre><code>  document.getElementById('my-item-name').value = meat.join("\t").veg.join("\t").sause.join("\t");
</code></pre>

<p>the variables are meat, veg, and sauce.</p>

<p>thanks</p>
