The userbox requires one parameters, the number of German federal states visited. Setting the value to 0 results in the word "none" in the text; setting it to 16 results in "all". An optional second switch (de) can be used to change "federal states" to the German "Bundesländer;" English is the default, although an "en" switch is also supported). A third switch changes the image from a flag-map (fm) to a map with the federal states shown in colors of the German flag (bl); if the third switch is used, the second one must be used too. For example:
{{User:Tcr25/Userbox/User German Länder Visited|0}}
{{User:Tcr25/Userbox/User German Länder Visited|8}}
{{User:Tcr25/Userbox/User German Länder Visited|16}}
{{User:Tcr25/Userbox/User German Länder Visited|4|de}}
{{User:Tcr25/Userbox/User German Länder Visited|4|en|bl}}
{{User:Tcr25/Userbox/User German Länder Visited|4|de|fm}}
