Just realized that the Superfecta Herold-Austria template does not work anymore. They changed the code on the website. This time my rudimentary skills are not good enough to adapt the template. Just reporting… 
The links for the search changed to (I think)
business
https://www.herold.at/gelbe-seiten/suche/?term=number
standard
https://www.herold.at/telefonbuch/suche/?term=number
Unfortunately, the result string changed too…and that’s the point where I have to give up…
A test link for business is
https://www.herold.at/gelbe-seiten/suche/?term=01206092544
and the test link for a standard entry is
https://www.herold.at/telefonbuch/suche/?term=017493216
The resulting numbers are displayed with the country code of Austria (+43), but just to pick up the names this seems to be not relevant. The search still works with the local area code e.g. 01 for Vienna.
