T_CONSTANT_ENCAPSED_STRING error

I viewed the custom_functions.php file (thesis theme) on a site. Without making any changes, I went to leave that area of WP and received the following error message: Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ‘)’ on Line 90. I copy/pasted the php code to Textpad and there is no line 90. I tried removing code and I still receive the error message. Any idea on what is causing it? The code is pasted 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.
