Error message

Hi,
I am hosting my website with Evohosting and have used their automatic wordpress install. They directed me here for help.

I have been trying to add social media buttons to my header.
I was following a tutorial on how to add a header widget area and was adding some code to the the function.php and I am now unable to access the dashboard and instead get this message:

Parse error: syntax error, unexpected ‘<‘ in /home/denisehu/public_html/wp-content/themes/sketch/functions.php on line 119

I had copied the original function.php text and pasted it back in thinking that it would resolve the issue – but I am still getting the same message. what should I do?
Any help or suggestions very much appreciated.
Denise
