Masking duplicates under 1 mask

ok, here’s the deal, i have a mask called [masker],
and a movieclip called [fotoframe]
the fotoframe is masked by masker. now i do

duplicatemovieclip(fotoframe, “fotoframe”+i, etcetc)
and movieclip.setmask(masker) for the just created duplicate,
(OK, inside a “while” thingy, among other things)

because i want all my duplicates under this one mask. but when i run it, only the last duplicated movieclip is masked…
How can i keep ALL duplicates under this one mask?

:pope:

This question has been asked and answered many times: put all your duplicates inside a container clip and mask the container.

sorry bout that, but erm, how do i do that?
