Add Widget to my site

I have a PHPBB forum. I have a widget that I would like to have displayed under the last forum of the board index page. Forums are added and deleted all the time. I need it added so that it always displays under the bottom forum. Here is the widget code <div class='fln-affiliate' data-username='thekingpingroup' data-style='' data-qts='//[login to view URL]' data-type='directory' data-theme='categoryFilter' data-size='' ></div> <script type='text/javascript'>(function(d) { var po = [login to view URL]('script'); [login to view URL] = 'text/javascript'; [login to view URL] = true; [login to view URL] = '//[login to view URL]'; var s = [login to view URL]('script')[0]; [login to view URL](po, s); })(document);</script> Attached is a photo of where on the fourm I want it to display
