Widget Interfering with Breadcrumb

I have a widget that is interfering with my breadcrumb in that it is causing my breadcrumb to show a path as if it were from a different page. An example, it should be getting the post id from the URL but instead it is hard coded to post_id=4. I noticed that when I changed post_id in my widget, the breadcrumb then reflected that change. I have pasted the code from my widget and from my breadcrumb below. Any ideas on how I can make sure the to do not interfere with one another?
