<p>I cannot provide any code because I feel it will take the thread away from the root question and lead to suggestions for hacks, jquery, or workarounds. I need to learn what is implied or causes the error </p>

<pre><code>Uncaught ReferenceError: Invalid left-hand side in assignment
</code></pre>

<p>Thanks in advance for any information as I cannot find it in any ref pages, tutorials, or documentation.</p>
