sharing my website on facebook

Hello I'm trying to share my website on facebook, I'm using asp.net and masterpages.

I've put a text in the meta tag but it doesn't appear on facebook

What appears is the text that is originally put in the meta tag, but I want to be able to change the metatag for every page but that isn't working.

The url of the website is [You must be registered and logged in to see this link.]

This is a test site and has only one button, the share button

What appears is the text that is originally put in the meta tag, but I want to be able to change the metatag for every page but that isn't working.

You mean this tag?

Code:

<meta property="og:description" content="Lots of text."/>

I don't get your question..

I'll try to explain myself better

In the master page of my website I have these metatags:

Code:

<meta  name="metaTitle" content="This is the Title" id="metaTitle" runat="server" />
    <meta name="description" content="This is a short summary of the page."  id="description" runat="server"/>

I have a content page where I want to change the content into something descriptive for the page like this:

Code:

((HtmlMeta)Master.FindControl("metaTitle")).Content = "Titill test";
        ((HtmlMeta)Master.FindControl("description")).Content = "lýsing test";

This works perfectly in my website, but facebook doesn't take notice of the changes and keeps displaying the old contents, that is from the master page

Actually I have another example where facebook continue to display static text which I have commented out days ago.

Hope you understand my problem better now

The url I sent you was a test page which I created because I couldn't get this to work

My real page is [You must be registered and logged in to see this link.]

it has the same problem
