Removing reviews for specific payment package

Morning Oh-wise-ones,
I have just been following the advice from https://wpgeodirectory.com/support/topic/disable-reviews-by-prices-and-payments-package-type/

And am adding the code to the child functions.php

// add the package id to the body
add_filter( ‘body_class’, ‘my_add_package_class’,10,1 );
function my_add_package_class($class){
global $post;
if (geodir_is_page(‘detail’) && isset($post->package_id)) {
$class[] = “gd-package-id-“.$post->package_id;
}
return $class;
}

.gd-package-id-2 #reviewsTab {display: none !important;}

and it states that there is a syntax error, unexpected ‘.’ in the last line…

As you can tell I am not very techie with this so any help with this will be gratefully received 🙂

Cheers,
Helen
