How can I say n.d.[<date>] in the Publisher Information?

[coulonnus]

e.g. n.d.[1820] when 1820 is the date claimed by the library from which I import a score. At present, after I upload a score with the new "skin", the Publisher Information field looks like {{P|Pelicieu||Paris||||}} but if I insert 1820 middle of |||| I obtain:
Expression error: Unrecognised punctuation character "["th century]] l

The pipe after the city is where the no date year goes. You have to manually change this in "Edit" after uploading. The uploader right now for the year only works for definitive dates, not approximate.

Do you mean I have to express this field à la old skin, i.e. Paris: Pelicieu, n.d.[1820]?

Simple if there is no plate, otherwise I remove the plate from its right place and say: |Publisher Information={{P||Melles Erard|Paris||||}}[1804] Plate 451.

If you go into edit, the placement of the "n.d." would be like this from your example:

{{P|Pelicieu||Paris|n.d.[1820]|||}}

The plate number goes three pipes after

{{P|Pelicieu||Paris|n.d.[1820]|||451}}

Thanks. It works when I edit an existing work page, but will it be possible if I upload a new work under the modern skin? I have no new work at this moment to do the test.

When I added http://imslp.org/wiki/6_Romances,_Op.19 ... %C3%A7ois) I obtained Expression error: Unrecognised word "n"th century]]. I had to edit the page and move the last | before n.d. as you said.
