Modify facebook share url link (add value in description)

Hi, I have a joke script that test couple affinity between two facebook profiles and shows a result with a %: I need to modify/customize the facebook share link that actually share the final result. At the moment, the working script share the result via [login to view URL] script, that put into facebook: title: "title of service: name1 + name2" description: "standard description of the service" link: the link of the single page. Every attempt with two names generate an unique page, like /script/[login to view URL] image: a default image What to change: title: ok, nothing to change description: I need to add the result of the compatibility (ex: 55%). So became: standard description + result link: switch from link of the single page to link of the home of the service (from /script/[login to view URL] to /script/ ) image: (optional, only if not expensive) the image actually shown in the single page /script/[login to view URL] for example or one of the two images scraped from facebook profile when the script run. I repeat: this feature is not a must. So please bid for modifiy/add a facebook share url link that A) add the % result in the description B) switch the ref url to the home. About image extra work change drop a line in your PM, like "for image extra work should add $$ to my bid" Important note: now the script is on a standalone subfolder, but in the future I'm planning to shows the script inside a wordpress page by using a custom template. I don't know if is important now, but keep in mind when you modify/develop the facebook share url link. In the attached "data for fc" you could find the link to the working script, and some other useful notes that will help you to understand the script. Thanks
