price don't change when choose different options

Hi,

Without a link to your product page, it will be difficult to say.
It could be a lot of things, like some javascript errors, some view overrides, etc.

Hi,

I checked your product page and as far as I can see, the price switching is working fine and it just looks like no prices are configured in the variants of your product.
Please provide a backend access via our contact form with a link to this thread so that we can check your product settings.

Hi,

I got the access. I wanted to check your product page again but the link you provided doesn't work anymore.
So I've checked with a different product:
www.developpementperso.com/upgrade/index...duct&task=show&cid=6
And actually, it is already correctly configured, and already works fine. I see the price change on the product page when I change the characteristic selection.

In your message, you also asked about the fact that you can't finalize the order.
I've done a test and indeed, I cannot finalize the orders: take.ms/7k8Tz
The Finish button is there once I login/register but there are no shipping methods configured.
