lost shopping cart functionality

Hi all
Have lost functionality of the shopping cart. Customers can add products but the cart wont move on to the next invoicing step. have been struggeling with this for some time and I am sure there is a simple expalantion where I have gone wrong

may be asking in the wrong section

Hi,

You just turned off the "show proceed to checkout button" option of your cart module.
Turn it back on and you will see the button again.

having a total mental blank at the moment where do I find the cart module

configuration/main/cart?

You'll find this option in Display>Content Modules>HikaShop Cart Module

found it many many thanks for your prompt and enlightening reply
