Missing City in Buyer Invoice and Documents

I already invested lots of time trying to locate an error made by exchanging City/Zip to ZIP/City in the documents raleted to Sales.

In the User "Address Book Entries" Section, I had no CITY Entry anymore. Also, No City was quoted on Invoices, created after the Modifications I have made somewhere. In older Sales-Documents, Addresses where present as they have been stored a while ago. after investing about 15 hours into nothing, I found the problem, I just forgot to enter the City into the Address Format in the Admin / System / Country Section.

Now, it looks like this and it works...

{company}
{firstname} {lastname}
{address_1}
{address_2}
{postcode} {city}

I leave this posting here for Fool's like me, trying to get to know PHP Scripting by Trial & Error, still, picking up a little day by day ...
