Unexpected $end in functions.php – Need help

I might be in serious trouble here. I try to add some sidebars in my functions.php file adding some code.

The original was:

<?php

if ( function_exists('register_sidebars') )
	register_sidebar();

function widget_mytheme_search() {
?>
<li>

<form method="get" id="searchform" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<p><input type="text" value="<?php echo wp_specialchars($s, 1); ?>" name="s" size="15" id="s" class="field" /></p>
<p><input type="submit" id="searchsubmit" value="Søk" class="button" /></p>
</form>
</li>
<?php
}
if ( function_exists('register_sidebar_widget') )
    register_sidebar_widget(__('45 Degrees Search'), 'widget_mytheme_search');
?>

Tried to add some sidebars using this code:

<?php

if ( function_exists('register_sidebars') )
	register_sidebar();
	register_sidebar(‘2′);
	register_sidebar(‘3′);
	register_sidebar(‘4′);

function widget_mytheme_search() {
?>
<li>

<form method="get" id="searchform" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<p><input type="text" value="<?php echo wp_specialchars($s, 1); ?>" name="s" size="15" id="s" class="field" /></p>
<p><input type="submit" id="searchsubmit" value="Søk" class="button" /></p>
</form>
</li>
<?php
}
if ( function_exists('register_sidebar_widget') )
    register_sidebar_widget(__('45 Degrees Search'), 'widget_mytheme_search');
?>

That one messed up everything and I’ve got this error:

Parse error: syntax error, unexpected $end in …../wp-content/themes/45degrees/functions.php on line 20

Ok, I replaced that one with the original to get rid of the error, but that error is still there. What shall I do? Need serious help here!
