I need the last day of every month. for the links in the archiv

Archiv

february (2008)
january (2008)
december(2007)

it works fine with december. i get the last dayof the entrie it is
29.12.2007

for january i only get the 1 day of the entrie the rest of the entries
are ignored
the same by feb.i get the first entry and rest are ignored.

if I take the Group by out off the quuery, I get them all,
but all 10 for jan and all of feb etc.,

iwant it like I show it in the example.
only one link per month. there should be the last day with an entry of
the month.

i hope I formulate verything so that you can understand it.

thanks for help

bye
Matt
