Cart variants not changing price in cart

[tratcliffe]

Hi,

vm 2.012f

clean install joomla 2.57
clean install vm + vm aio

1 product created - 1 custom field created - cart variant, extras.
I added to the product.

The price changes in product detail.
The price does not change in cart or in cart module.

any help gratefully accepted - with fresh install, one product, this should be easy.

here is the live site :-

demo/demo will get you in the back end.

cheers in advance

Trevor
