Hello Guys,

I am using virtuemart3..0.4 with joomla version2.5. I have installed one page checkout extension and EU vat checker plugin.
My requirement is that

1)Dutch customers always need to pay vat
2)EU customer - when valid VAT ID - no vat - when invalid VAt - need to pay vat
3) No eu customer - no vat

I  tried lot of settings but it dosen't worked for me. Please help with that. I am in huge trouble with this.

For support for 3rd party extensions you must ask the developers
http://forum.virtuemart.net/index.php?topic=108212.0

and if you bought our plugin, please ask here

But before you ask us, disable the 3rd party OPC, test THEN the euvatid plugin.
