Hello,

Code below:

<!--slider section -->
<b:if cond='data:blog.pageType == &quot;index&quot;'>
<b:section class='slider' id='Slider' maxwidgets='2' showaddelement='YES'>
  <b:widget id='HTML7' locked='false' title='Slider' type='HTML' version='1' visible='true'>
    <b:includable id='main'>
            
<!-- Slider Container -->
<div id='main-slider'>

<script>
document.write(&quot;<script src=\&quot;/feeds/posts/default/-/&quot;+cat1+&quot;?max-results=&quot;+numposts1+&quot;&orderby=published&alt=json-in-script&callback=showrecentposts1\&quot;><\/script>&quot;);
					 </script>

</div>
