I am facing a strange problem and have no idea how to fix this since i am new to magento. The Add-to-cart button is not working on the product details page here

But it's working on the category page here

Why can this be happening. I have given the links above so that you can see the button code and tell me if somethings getting wrong.
EDIT
I removed the declaration for jquery library and my navigation file. Then the add to cart button started working. What i need to know is why does thing works well in localhost. Same files, same library and same code, but they just seem to encounter a conflict on server. Please suggest something
