All in one SEO not showing Homepage description

I am using the latest wordpress ver with 2.2 ver of AIOSEO for my website https://www.smeng.com. I have entered Title n Desc for home page but only the Desc tag is not showing up in the view source code. Although the plugin is working fine with other pages. I am not very much familiar with coding so here I am pasting my header.php code:

If anyone can detect the issue kindly point out and do let me know how to fix it. Thanks

<?php

if($_SERVER[‘REQUEST_URI’]== “/”){ ?>
<title>Utility Rate Analysis – Get the Best Energy Rates</title>

<?php }
elseif ($_SERVER[‘REQUEST_URI’]== “/blog”) { ?>
<title>Articles on Energy Costs and Utility Management</title>
<meta name=”description” content=”Our blog section covers articles on energy rate options, tips to improve energy efficiency, cost reduction, utility bill audit, management and tax exemption laws” />
<?php }

else { ?>
<title><?php echo strip_tags(the_title(”,”,FALSE)); ?></title>
<meta name=”description” content=”<?php $metadesc = get_post_meta($post->ID, ‘_aioseop_description’, true);
if ($metadesc) {
echo $metadesc;
} else {
the_excerpt();
}
?>”>
<?php } ?>

[ No bumping please. ]
