Posting on LinkedIn

In a PHP page I added the AddToAny LinkedIn button using the below code. The button is supposed to read from URL page and post that page content to my LinkedIn. But it is not working.

I am always getting a small window in which I see the logo of my site which is going to be shared on LinkedIn. Only when I click that LinkedIn post, I get the URL content I wanted to post in the first place.

My code:

       <p>
            <div class="a2a_kit a2a_kit_size_32 a2a_default_style" data-a2a-url="New_User_Profile/newuser.php" data-a2a-title="Share my profile">
                <a class="a2a_button_linkedin"></a>
            </div>
        <p>

The page I need help with: [log in to see the link]
