Parse Error Please Help!

Parse error: syntax error, unexpected ‘<‘ in /home3/aimeeyor/public_html/wp-content/themes/spacious/functions.php on line 121

I get the above error. I have very limited knowledge of coding, I am desperate Please Help! I was trying to get rid of the “You can use the following HTML Tags” below the comment box, by adding the code:

<?php comment_form(array(‘comment_notes_after’ => ”)); ?>

into the function.php , but I obviously had no idea what I’m doing and now I’m shut out of my site! Any help please!
