When I attempt to upload my custom_functions.php file to my website via ftp that works fine and it takes effect on the website. The one problem is I get an error when I look in the file editor for that file inside wordpress and it says that error on the website. I am not to familiar with any coding language so I don't know what the error is for the file. If someone who is familiar with coding could take a look at it and let me know, that would be great. The error I get when the file takes effect on the website is

The custom_functions.php file I copy and pasted down below.

// Using hooks is absolutely the smartest, most bulletproof way to implement things like plugins,
// custom design elements, and ads. You can add your hook calls below, and they should take the
// following form:
// add_action('thesis_hook_name', 'function_name');
// The function you name above will run at the location of the specified hook. The example
// hook below demonstrates how you can insert Thesis' default recent posts widget above
// the content in Sidebar 1:
// add_action('thesis_hook_before_sidebar_1', 'thesis_widget_recent_posts');

// Delete this line, including the dashes to the left, and add your hooks in its place.
