The only point I was making about another joomla template that had VM installed with a few product samples is that they are 2 arbitrary sites with the same problem. So a problem (or bug) exist.
So I have shown you the edit order section (pic) a few times so here is the tax setup along with the config in product BE plus product FE.
Setting up pricing with just a cost or base price doesnt solve or change anything. It still does not work for tax per bill on the orders edit page.
I did find another VM topic talking about the exact same problem but with no answer.
http://forum.virtuemart.net/index.php?topic=136852.msg497109#msg497109The cart set up as I have it works perfectly. Its only the order edit page.
I feel pretty certain there is no tax per bill row set up on order page to actaully do calculation.
VAT tax falls in a completely different location on the orders page and seems to calculate completely different pricing variables.(perhaps discount totals?) Not sure how VAT works....
