Not that I understand how talkback works, but (scroll down!):

Here is some text

[edit]

Test of references.[1] Maypraps they don't work between an infobox[2] and the main text[3]. Seems a pity. More text to add a reference to.[4] This is probably enough text to see if the reference has worked or not.

Bottle bill

In 1971 a blah cost on average $0.05. This is equivalent to $Format price error: cannot parse value "Error when using {{Inflation}}: |index=GB (parameter 1) not a recognized index." in present day terms.[1]
