broken website help with function.php

I have broken my boss’s website. HELP! I tried to add some code to the functions.php file to make menus natively supported but I have never used code or wordpress before and have no idea what i’m doing.

Now the website shows the following error and also I can no longer login to wordpress.

Parse error: syntax error, unexpected $end in /home2/desaiarc/public_html/wp-content/themes/desaiarchitecture/functions.php on line 66

the site was set up in google apps apparently. Can anyone advise me what to do to resove this. I really appreciate your help. thanks
