Hello,
This topic http://forum.virtuemart.net/index.php?topic=128671.msg442382#msg442382 described my problem. The solution is to set the progressive calculation off.
Where can i set the progressive calculation off?
Note: I'am using a payment plugin. Must it be done in this plugin? Or is it a Virtuemart configuration item??
Regards Michel
Cost method calculation is a setting in the PM PayPal plugin - if you use that.
