Site Down: Parse Error in functions.php.

Hi,

I was editing my theme’s functions.php in the wordpress theme editor, and at some point the site went down and just shows an error message;

the site is;

http://www.regasstudio.com

I tired copying and pasting the parent theme twentyten’s functions.php to the custom child theme’s functions.php, copying from other custom themes… nothing works. I just want the site back…!

Please help!
