Problems with weekly digests

I just found out that people don't seem to be getting the digests if they 
asked for them to be weekly. Here is my digests setting.

configset framcom digests <<ENDAAC
daily
times=5
minsize=1
minmsg=1
maxmsg=200
maxsize=0
maxage=1d
minage=0
newmsg=0
desc=The framcom daily digest
subject=[$LIST] Daily digest ($MESSAGECOUNT messages)

weekly
times=fr(23)
minsize=1
minmsg=1
maxsize=0
maxmsg=400
type=mime
desc=The framcom weekly digest
subject=[$LIST] Weekly digest ($MESSAGECOUNT messages)

ENDAAC


Am I doing something wrong? I need to fix this :-(

TIA
