Many thanks for the hints!
But the links don't work properly. If I have a URL, for example xyz.com/document.pdf, and put the same URL as a link, it works. But if I have any text and put the link there, it doesn't always work, although it is placed in the afpub-file. (See the attached pdf. All "Foto X"-Texts have a link, but not all work. If you look in the right column, it says "Department of Theological Concerns der Weltweiten Evangelischen Allianz". After that there is a URL. Although the URL is "www.worldevangelicals.org/pdf/....pdf" and is set in the same way in afpub, the page "www.worldevangelicals.org" is called.
