Product price is not changing

[Ruup]

Hello.
Iam sorry if my english is not so good, Iam from the Netherlands.
I have made a shopping cart variant that raises the product price, if you select it from the dropdown. The problem is it doesn't update the price. Maybe there's something wrong with javascript? Also the shopping cart variant is not visible in the shopping cart itself. I updated my shop from virtuemart 2 to virtuemart 3 and in VM2 it was working right.I hope someone can help me.

It has something to do with my template.
I changed my template to beez3 and the prices are changing when i select an option from the dropdown.
Does anybody know how the error in the template can be repaired?

If it is a commercial template then ask the template developer. It may not be VM3 compatible.  http://forum.virtuemart.net/index.php?topic=108212.0
