Alowing Widgets for Archive Page

Hi.

I use your theme for a property site and on a search to look for properties, it directs to an archive page where there are no sidebars. Is there a fix for this please?

Here is a link to see what i mean. http://richard-blake.co.uk/?action=epl_search&post_type=property&property_status=&property_id=&property_location=&property_price_from=&property_price_to=&property_bedrooms_min=&property_bedrooms_max=

Thanks.
