Parse Error

I stupidly tried to edit the .php file to increase the width of my header for optimized viewing on the ipad. I know I shouldn’t have, since I don’t know what I’m doing. I now have the following error: Parse error: syntax error, unexpected ‘,’ in /home/czdesign/public_html/wp-content/themes/brunelleschi/functions.php on line 437

I no longer have access to my site, so I have no idea how to fix this. Can’t even figure out how to get “live” help for someone to walk me through this. I am a beginner and don’t know what I’m doing. Thanks for any help.
