The standard VM Invoice PDF has company address at the top left using tag {contact}. Part of it shows "state" Pennsylvania which in my shop is not relevant. I cannot find this in Joomla or Virtuemart. Where is the content for {contact} taken from? I am a beginner and for future purposes, is there a general way in which I can see from where a given tag gets its content?

I replaced {contact}, which is ok for the U.S., but not good for most European countries, with the replacement fields for vendor i.e. {vendor_company_name} etc.

Problem solved.
