Adding right side bar to Product theme

Hi there,

I am trying to add right side bar to product theme on the pages, I modified the function and registered registered the sidebar, modified the css but it is overlapping sidebar block above footer. All modifications files are in the child theme.

Also I want to add the WP Sponsor Flip Wall (<?php wp_sfw_render(); ?>) to my page template but it keeps displaying over the lower sidebar instead of within the content area.
need some help here.
