Of course thanks again for the precious information you gave me.
Concerning the Author2xml file I took a look at it and, at glance, it seemed to be very difficult to me.
I understood what you mean but I remember in the previous version of Word, when I used Vancouver with Word 2010, in order to solve my little problem I adjusted the following script:
</source>
<source type="JournalArticle">
<column id="1">
<halign>right</halign>
<valign>top</valign>
<format>{%RefOrder%.}</format>
</column>
<column id="2">
<halign>left</halign>
<valign>top</valign>
<format>{%Author:1%. }{%Title%. }{%JournalName%. }{%Year%{ %Month:s%{ %Day%}};}{%Volume%}{(%Issue%)}{:%Pages%.}{ %DOI%.}{ %Comments%.}</format>
</column>
<sortkey></sortkey>
</source>
simply I changed %Author:1% for %Author% without :1 and it worked greatly till I installed the new version: Word 2013;
It was immediate: I copied and pasted the list of Author and it appeared in the final reference as I had inserted it.
(as you see I made few other changes in that script to fit the final appearence of the reference)
Eventually, if there is nothing to do I will probably add something like: “standardnumber” in the place of Author where I will paste the list of Author so as to rapidly fit the result.
With regards to the narrowed form of the preview I attached a screenshot with an arrow to the problem. Sorry but as you see my version is in italian language.
I am looking forward to hearing from you.
Best wishes.
