Dreamweaver Spry Bar problems

[Nicole Maxx]

This is my first real website, so please forgive my lack of knowledge, I am trying. Please ask any questions if I do not explain my problem well enough.
This is where you can find my in progress site http://www.maxxsunglasses.com/development/MaxxWeb2010/products.html
When I click on products or about us or company info, the link will add that to the URL i.e. http://www.maxxsunglasses.com/development/MaxxWeb2010/products/products/cinco.html
Sometimes it seems to work fine, but only if I have only be in the products pages.
Is this a code problem, do I need to have everything in one folder, and not use subfolders? Thank you so much in advance for your help.
