JQuery - show/hide isn't working

Question

So I've done a show/hide script that open and closes the element that's being clicked. But now I can't get it to work somehow and i can't figger out why.

Can someone try take a look at it?

HTML

<div id="fleresvar" class="fleresvar">  <u><b>Klik her for at se flere svar</b></u>

    <div id="txtmore" class="txtmore" style="display:none;">
        <div id="txtask1" style="text-decoration:underline;color:#8F8F8F;cursor:pointer;"></div>
        <div id="txtask2" style="text-decoration:underline;color:#8F8F8F;cursor:pointer;"></div>
        <div id="txtask3" style="text-decoration:underline;color:#8F8F8F;cursor:pointer;"></div>
        <div id="txtask4" style="text-decoration:underline;color:#8F8F8F;cursor:pointer;"></div>
        <div id="txtask5" style="text-decoration:underline;color:#8F8F8F;cursor:pointer;"></div>
</div

JavaScript

$("#fleresvar").click(function () {
    var $element = $(this);
    if ($(this).hasClass('open')) {
        $element.removeClass("open");
        $element.children(".txtmore").hide(500);
    } else {
        $(".open").removeClass("open");
        $('.txtmore').hide(500);

        $element.toggleClass('open');
        $element.children('.txtmore').toggle(500);
    }

});
