Price doesn't update

[vlasmar]

Hello

My site is
http://rosmarino.gr/joomla/index.php/el/shop-store-gr/%CE%B5%CE%BA%CF%87%CF%85%CE%BB%CE%AF%CF%83%CE%BC%CE%B1%CF%84%CE%B1-%CE%B2%CE%BF%CF%84%CE%AC%CE%BD%CF%89%CE%BD

I have a problem with custom fields. I want two options for a product with different prices.

I want
50ml 5.5€
100ml 11€
I put them as string custom fields but the price doesn't change.

You need to update your template overrides to include 'product-container' class http://virtuemart.net/news/latest-news/477-release-of-3-0-18-connecting-the-loose-ends.
