Joomla 3.4.0
VirtueMart 3.0.6
ARTIO VMInvoice 3

When I change a price under calculations, in the price line it changes to zero, no matter what price I enter in "Cost Price." If I attempt to use price override, it just hangs. And the subtotal keeps the original price.
Is this a known bug?
What can I do to fix it?

Problem Solved:
There were a couple of syntax errors in the Danish Language file I downloaded from Transifex. After going through line-by-line, and correcting them, the PDF now generates fine.
I'm attempting to attach the working Danish Language files in a .zip, if anyone else needs them (though one of the admin files is incompletely translated)

Oh, Joomla 2.5.9, PHP 5.3.15, Artio VM Invoice Version 2.0.24.

I'm sorry if I'm missing something, but I have read in the forums various language issues and most of the answers involve things I've already tried. (I haven't altered any source php, but if it comes to that I'd like to know exactly which file and what to change.)
When the site is set to Danish, nothing except the contact info and logo goes to .pdf (attachment a)
When the site is set to other languages, eg English or German, works fine: (attachment b)
But when in debug mode in Danish, does seem to pull the information: (attachment c).
So, it's getting the info from the language file, but won't print it to a .pdf?
What am I missing here?
Please help!
