Can't preview my posts or edits to posts

When writing a post, I’m just trying to preview what I have done and everytime I hit the ‘preview changes’ button, in the new window that opens up, the following error displays:

Parse error: syntax error, unexpected ‘;’ in /home/thrivea6/public_html/wp-content/themes/twentytenTHRIVE/single.php on line 60

I am not sure what is wrong on my single.php which isn’t allowing this. But here is my ‘single.php’ file. If someone could help me with this it would be greatly appreciated. Thanks
