can you show what product variant you have configured (screenshot)
or a screenshot of the product with the standard template?
have you read thru this how to?
www.flexiblewebdesign.com/forum-virtuemart-2-template-puremart-support/152-tutorial-custom-field-with-stockable-variants
or is this a child product?
on another topic - where did you get the nice accordian VM cat menu?
asked
offlajn.com but they say theirs only has flyout (as on their demo) - did you hack this ?
cheers
