Getting jquery error like "not a function"?
<p>I'm getting a JavaScript error saying <code>$tabAcc.removeClass is not a function</code> when executing the code below. What could be the issue?</p>

<pre><code>var $tabAcc = '',
    $tabtoShow = '',
    $tabSelectAcc = '',
    $tabtoShowSelected = '',
    $tabSelectAcc = '',
    $tabBilling = '',
    $tabtoShowBilling = '',
    $tabSelectBilling = '',
    $tabtoShowBillingSelected = '';
$(".tabAcc").mouseover(function () {
    $tabAcc = $(".tabAcc");
    $tabtoShow = $tabAcc.children('.tabListMenu');
    $tabAcc.removeClass('tabAcc').addClass('tabHoverAcc');
    $tabtoShow.show();
}).mouseout(function () {
    $tabAcc.removeClass('tabHoverAcc').addClass('tabAcc');
    $tabtoShow.hide();
});
</code></pre>
