Thanks Dr Byte, that did the trick.

Just one interesting thing.. when there is only one shipping method available to a user it has a pre-selected radio button next to that one shipping option.

For the payment module, in my case Im only allowing Paypal for certain countries - the payment module was visible as I was checking out but not 'selected' by way of a radio button or checkbox.

I know that doesnt stop me from checking out, but I must admit, it really threw me for a few minutes - I could see the payment method and thought (incorrectly) that I had no way of selecting it.

Just my 2c
