Getting "--> ;" on front page after editing custom html.tpl file I am newbie and using Drupal - 7.

I have added script tags into my customized html.tpl file.

&lt;script async src="http://i.simpli.fi/dpx.js?cid=0&amp;segment=Segment+Name&amp;campaign_id=0"&gt;&lt;/script&gt; 


And now I am getting this "--> ;" into front page of my website.

This is the code for my customized html.tpl. file with script tags.

&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN"
  "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd"&gt;
&lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="&lt;?php print $language-&gt;language; ?&gt;" version="XHTML+RDFa 1.0" dir="&lt;?php print $language-&gt;dir; ?&gt;"&lt;?php print $rdf_namespaces; ?&gt;&gt;
&lt;head profile="&lt;?php print $grddl_profile; ?&gt;"&gt;
  &lt;?php print $head; ?&gt;
  &lt;title&gt;&lt;?php print $head_title; ?&gt;&lt;/title&gt;
  &lt;?php print $styles; ?&gt;
 &lt;!-- &lt;?php print $scripts; ?&gt; --&gt; 
&lt;/head&gt;
&lt;body&lt;?php print $attributes;?&gt;&gt;
&lt;?php print $scripts; ?&gt;
&lt;script async src="http://i.simpli.fi/dpx.js?cid=0&amp;segment=Segment+Name&amp;campaign_id=0"&gt;&lt;/script&gt; 
  &lt;div id="skip-link"&gt;
    &lt;a href="#main-content" class="element-invisible element-focusable"&gt;&lt;?php print t('Skip to main content'); ?&gt;&lt;/a&gt;
  &lt;/div&gt;
  &lt;?php print $page_top; ?&gt;
  &lt;?php print $page; ?&gt;
  &lt;?php print $page_bottom; ?&gt;
&lt;/body&gt;
&lt;/html&gt;


Can anyone please help me?

Thanks!
it is probably stemming from this line:

&lt;!-- &lt;?php print $scripts; ?&gt; --&gt; 


&lt;!-- --&gt; is a commenting system for HTML, but the item you are trying to comment out is php, which uses a different method for commenting.

you would use the html commenting around html elements:

&lt;!-- &lt;div&gt;Hello World!&lt;/div&gt; --&gt;


whereas for php:

&lt;?php //print $scripts; ?&gt;


or

&lt;?php /*print $scripts;*/ ?&gt;


would be appropriate.
