Is she using xl97 or later. Hyperlink was introduced in excel 97 I believe.
Weeknum is from the analysis toolpak, but not the hyperlink worksheet
function (to the best of my knowledge).

Hello,

one of the users, using my excelfile gets #NAME? instead of the hyperlink
and the link doesn't work for her (it works fine for every other user). The
formula is:

=HYPERLINK("#Planerat!R2C"&(WEEKNUM(NOW())-11); "Conversion")

I checked that she has the Analysis TollPak selected, because I suspect
that that is where the problem occurs, because in another cell I am showing
what week we have right now and that cell is also #NAME? for her. Anyone
knows what might be the problem?
