Custom fields

[Topknotch]

Hi All,
I recently upgraded virtuemart 1.19 to 3 using the migration tools.
Everything appears to have gone smoothly apart from the custom fields do not show on the product page, it also dosent affect the order i.e you can still buy the product even though it has 'attributes'
I have checked the product and all the custom feilds are in there but they do not have any affect.
The site is running joomla 2.5.28 and virtuemart 3.0.2
Thanks and apologies if this has been asked before but I couldnt find anything on the problem.
