"Uncaught ReferenceError: jquery is not defined" - but it is
<p>I've ready some similar questions and have verified that jquery is the first script included...</p>

<pre><code>// this test confirms that jquery is defined
if (typeof jQuery == 'undefined') {
    alert('jquery not defined');    
}
// (this is being alerted)
else { alert( 'jquery is defined'); }

// this is what I want to achieve (to begin with)
jquery("#free-signup").css( 'display', 'none' );
</code></pre>

<p>and jquery does seem to be defined... what am I doing wrong?!</p>
