Syntax Error in footer.php

Newbie here.

this the content of my footer.php

I get this error message on every page.

syntax error, unexpected T_STRING in /hermes/bosoraweb131/b736/ipg.housemeistercouk/artgroupcritique/wp-content/themes/slresponsive/footer.php on line 35

Here is the contents of the file, any help decoding the problem would be appreciated.

<?php
/**
* The template for displaying the footer.
*
* Contains the closing of the #content div and all content after
*
* @package slresponsive
*/
?>

<footer class=”footer”>
<?php if ( is_active_sidebar( ‘footer-top’ ) ) : ?>
<div class=”row”>
<?php dynamic_sidebar( ‘footer-top’ ); ?>
</div>
<?php endif; ?>

<?php if ( is_active_sidebar( ‘footer-middle’ ) ) : ?>
<div class=”row”>
<?php dynamic_sidebar( ‘footer-middle’ ); ?>
</div>
<?php endif; ?>

<?php if ( is_active_sidebar( ‘footer-bottom’ ) ) : ?>
<div class=”row”>
<?php dynamic_sidebar( ‘footer-bottom’ ); ?>
</div>
<?php endif; ?>

<div class=”row copyright”>
<div class=”twelve columns”>
<p>

<span class=”sep”> | </span>
<?php printf( __( ‘Theme: %1$s by %2$s.’, ‘slresponsive’ ), ‘SlResponsive’, ‘AwoThemes( ‘https://www.ads-software.com/&#8217;, ‘slresponsive’ ) ); ?>”><?php printf( ‘ ); ?>
</p>
