Help! Parse error stopped me cold

I edited the header.php file to attempt to change the header image, but now when I try to view the site I get this message:

Parse error: syntax error, unexpected T_STRING in /home8/todaysc1/public_html/wp-content/themes/tropicala/header.php on line 40

URL is https://www.todayscrafter.com

Worse yet, I closed the window and now don’t know how to get into the dashboard or anything. Help!
