How to add link to LinkedIn in footer?

[Walrus]

I found a topic but not allowed to reply. Topic shows how to add LinkedIn URL but I thought I would try to expand the Social Networking Module page in back office. When I add following to blocksocial.tpl in my custom theme's modules:

 

 {/if}

                {if isset($linkedin_plus_url) && $linkedin_plus_url != ''}

        <li class="linkedin">

        <a href="{$linkedin_url|escape:html:'UTF-8'}" class="btn-tooltip _blank">

        <span>{l s='LinkedIn' mod='blocksocial'}</span>

        </a>

        </li>

 

I expect an option to fill URL to appear in the 'Social networking block v1.2.1' module page but it doesn't. Any idea why?

 

The other options are there: Facebook URL, Twitter UR, etc.

 

Thanks.
