Hey @artsyg 

Looks like your code is missing the starting bracket

id="MainProduct-template--20427820040485__main" class="page-width section-template--20427820040485__main-padding" data-section="template--20427820040485__main" >

This should be

<div id="MainProduct-template--???" class="page-width section-template--???" data-section="template--???" >

I put ??? because i need to find out the exact code here.
