Need help with jQuery accordion

I created a site recently. I added near the top of the page a jquery accordion, that features 3 collapsing content panel. The first two ones are working fine but, something is wrong with the 3rd one. I just can't make it work.
The website is NYC Web Design. I really appreciate your help on that matter

Here is the code:

div class="sectionAcc">
 
            <!-- accordion -->
 
            <div id="accordion533" class="accordion">
 
                <div class="accordion-group">
 
                    <div class="accordion-heading">
 
                        <a class="accordion-toggle" href="#collapse749" data-toggle="collapse"><i></i>Ultra Clean & Modern Design</a>
 
                    </div>
 
                    <div id="collapse749" class="accordion-body collapse" style="height: 0px;">
 
                        <div class="accordion-inner">
 
                            <p>

                <div class="accordion-group">
 
                    <div class="accordion-heading">
 
                        <a class="accordion-toggle" href="#collapse750" data-toggle="collapse"><i></i>Mobile Compatibility</a>

            </div>
 
            <!-- / accordion -->
 
        </div>
 
        <!-- / sectionAcc -->

Code (markup):

 

Line #59 div id="colapse751" should be div id="collapse751".
Just a small typo.

 

Thank you so much. I really appreciate.
