jquery anchorSlider doesn't work on first click

Question

Hi, I have a link on my page that when clicked opens up two tabs below, I then want it to scroll down to an anchor on the same page using the anchorSlider plugin.

The problem I'm having is when I click my link, the tabs open, I have the click the link again to make the page scroll down.

Any idea how I can make it do both functions on the first click?

My code is as follows:

if($('span.opener').length) {
    $('span.opener a').click(function(){
        $('div.exp').each(function(){
            $(this).show();
        });
        $('div.togglewrap img').each(function(){
            if ($(this).parent().parent().hasClass("orange")) {
                col = "orange";
            } else if ($(this).parent().parent().hasClass("lightorange")) {
                col = "lightorange";
            } else {
                col = "white";
            }
            $(this).attr("src","/images/tab-"+col+"-close.png");
            $('p.header').animate({'padding-top':'30'},300);
        });
        $("span.opener a").anchorAnimate();
        return false;
    });
}

Thanks
