Using Panels and Views to Display Information from Entity Reference
First, you need to create a view (probably block display) of the sales surveys, with a contextual filter. Create a new view of Sales surveys, with a block display. Add whatever fields you want to the display. Then, open the "advanced" tab, and add a contextual filter:


choose the field that you've named as the entity reference to the store
provide a default value -> "content ID from URL"


Once you save that view, go into panels, and add that view to the page you are creating for the stores.
