[Plugin: Visual Form Builder] Customize the CSS

I am attempting to update the format of the form by making the following changes as outlined in the FAQ section of the Visual Form Builder:

How do I customize the CSS?

If you want to customize the appearance of the forms using your own CSS, here’s how to do it:

Add this code to your theme’s functions.php file: add_filter( ‘visual-form-builder-css’, ‘__return_false’ );
Copy everything from css/visual-form-builder.css into your theme’s style.css
Change the CSS properties in your theme’s style.css as needed

I AM RECEIVING THE FOLLOWING ERROR MESSAGE WHEN I ATTEMPT TO UPDATE THE FUNCTIONS.PHP FILE:

Parse error: syntax error, unexpected ‘}’ in /home/rosti57/public_html/testing/wp-content/themes/wp-davinci-20/functions.php on line 245
