Check if Meta Tag Quick Description Is Set

Hi,

I'm using this module to set meta descriptions on paths that are views. Within another meta tag module I'm using I would like to check and see if the meta tag quick meta description is set for the current node or view to prevent creating two meta descriptions. To make sure the meta tags module didn't do this I used this:

if (!isset($node->metatags['description']['value'])) {
drupal_add_html_head($meta_description, 'meta_description');
}

Could you point me in the right direction on how to do this with meta tag quick? Still figuring out how this all works in Drupal 7.

Thanks
