[NTG-context] page references (varioref)

Hello, I tried to implement something like the LaTeX varioref package, but without success. In detail: I would like to create a command like \at[], say \VarioAt[], that outputs a text in function of the page-number, for example: * if page is the same as the current page: "on the current page" * if page is next page: "on the following page" * if page is previous page: "on the preceding page" * else "on page XX" (XX is page-number) I tried with something like \doifelse{\expanded{\at[myRef]}}{\expanded{\currentpage}}% {same page}{different pages} But it seems, that this does not work... :( Could you help please?
