Hi, I know I asked the question a few years ago, but I don't remember ! The idea is to test whether the document contains only one page or not.
Perhaps not the nicest solution, but this works:
\doifvalueelse {\lastpage} {1} {\message{true}} {\message{false}}
Same solution but better counter name:
\doifelse{\totalnumberofpages}{1}{...}{...}
