Error Code on ColorMag Theme

I was tryin to add an email subscribe box to my header and only after attempting to do so found out that the header is not supposed to be edited. I deleted the code I added but something went wrong and now I get this code.

Parse error: syntax error, unexpected end of file in /home/content/p3pnexwpnas10_data01/55/2689455/html/wp-content/themes/colormag/inc/header-functions.php on line 72

I can get to my dashboard but any attempts to get to the theme, plugins or even main page of the site are blocked by this code. PLEASE HELP!
