I downloaded a template to a Blogger blog and I wanted to remove some parts of a static post details like the tags and author and just want to display the post thumbnail, post title, number of comments and summary of the post. I drew it so it will a lot more understandable. It looks like this by default:

I found out that in this template, they use this script to display these static pages:

<b:if cond='data:blog.pageType != "static_page"'> <b:if cond='data:blog.pageType != "item"'> <div expr:id='data:post.id'> <data:post.body/> </div> <script type='text/javascript'> var post_title="<data:post.title/>", post_url="<data:post.url/>", author_name="<data:post.author/>", author_url="<data:post.authorProfileUrl/>", comment="<data:post.numComments/>", label="<b:loop values='data:post.labels' var='label'><a expr:href='data:label.url + "?max-results=6"' rel='tag'><data:label.name/></a><b:if cond='data:label.isLast != "true"'>,&nbsp;</b:if></b:loop>", time="<data:post.timestamp/>"; readmore("<data:post.id/>"); </script> </b:if> </b:if>

Whenever I edit that script, something will go wrong with the static item, it will lose its original look and it looks horrible. Below that code are these:

<b:if cond='data:blog.pageType == "item"'> <div class='blog-content-wrapper'> <div class='blog-content-inner-wrapper'> <header class='post-header'> <h3 class='gdlr-blog-title'> <a expr:href='data:post.link'> <data:post.title/> </a> </h3> <div class='gdlr-blog-info gdlr-title-font gdlr-info'> <div class='clear'/> </div> </header> <div class='gdlr-blog-content'> <data:post.body/> </div> <div class='single-post-bottom-info'> <div class='share-this-post social-icons-wrapper'> <a class='facebook' expr:href='"http://www.facebook.com/sharer.php?u=" + data:post.url' name='fb_share' target='_blank'> <i class='fa fa-facebook'/> </a> <a class='twitter' expr:href='"http://twitter.com/share?url=" + data:post.url' target='_blank'> <i class='fa fa-twitter'/> </a> <a class='google' expr:href='"https://plus.google.com/share?url=" + data:post.url' target='_blank'> <i class='fa fa-google-plus'/> </a> <a class='tumblr' expr:href='"http://www.tumblr.com/share/link?url="+ data:post.url' target='_blank'> <i class='fa fa-tumblr'/> </a> <a class='linkedin' expr:href='"http://www.linkedin.com/shareArticle?mini=true&url="+ data:post.url' target='_blank'> <i class='fa fa-linkedin'/> </a> <a class='stumbleupon' expr:href='"http://www.stumbleupon.com/submit?url="+ data:post.url' target='_blank'> <i class='fa fa-stumbleupon'/> </a> <a class='digg' expr:href='"http://digg.com/submit?url=" + data:post.url' target='_blank'> <i class='fa fa-digg'/> </a> </div> <br/> <br/> <div class='gdlr-post-author'> <h3 class='post-author-title'> About Post Author </h3> <div class='clear'/> <div class='post-author-avartar'> <img alt='' class='avatar avatar-125 photo' expr:src='data:post.authorPhoto.url' src='http://i.imgur.com/hgQVqzg.jpg' style='width:125px;'/> </div> <div class='post-author-content'> <h4 class='post-author'> <a expr:href='data:post.authorProfileUrl' rel='author'> <data:post.author/> </a> </h4> </div> <div class='clear'/> </div> <div class='gdlr-related-post-widget'> <h3 class='related-post-title'> You may also like </h3> <div id='related-posts'> <b:loop values='data:post.labels' var='label'> <script expr:src='"/feeds/posts/default/-/" + data:label.name + "?alt=json-in-script&callback=related_results_labels"' type='text/javascript'/> </b:loop> <script type='text/javascript'> removeRelatedDuplicates();printRelatedLabels('<data:post.url/>'); </script> </div> <div class='clear'> </div> <div class='clear'> </div> </div> </div> </div> </div> </b:if> <b:if cond='data:blog.pageType == "static_page"'> <div class='blog-content-wrapper'> <div class='blog-content-inner-wrapper'> <header class='post-header'> <h3 class='gdlr-blog-title'> <a expr:href='data:post.link'> <data:post.title/> </a> </h3> <div class='gdlr-blog-info gdlr-title-font gdlr-info'> <div class='clear'/> </div> </header> <div class='gdlr-blog-content'> <data:post.body/> </div> </div> </div> </b:if>

Whenever I edit something on the static <b:if> , nothing happens to the page. Again, my problem is that I cannot modify anything in this static page.

I really don't know how to do this so I hope someone can help me.
