Side bar issue with page categories

After many hours working on this website – this is my last hurdle. (I hope)

I realized that with the WP e-commerce plug-in, and further more with the WP e-commerce grid view plug-in, that sorting by “categories” in my store takes me to pages that I can’t find to edit the sidebar.

Example: On my store page you can select in the sidebar to only look at say, reptiles. This takes you here where the side bar has changed back to the default one. This makes user navigation difficult. I need my “store nav bar” visable on these sub-category sites.

Where do I start? Please help!

Thank you 🙂
