Indexing List news

hi,

I looking some information because, I installed the plug-in but it doesn’t working. I took a free template that I had customized (I pretty sure it’s my code that it doesn’t working well with the nav).

When I put the link : <?php if(function_exists(‘page_navi_slider’)){page_navi_slider();}?>, in my page or footer or what ever, nothing happen.

I would like the Nav of the two pages of my list of news, on this page:
site
