Yep!!!
On the summarization statement
AREA areaid# RANGE address address-mask
but I think the statement
network ospf 23
is suppose to be ...
ROUTER OSPF 23
I used the wildcard .3 to define the network
AND!!!! my cut and paste of yours brought another error
route
it should read
NETWORK address wildcard-mask AREA area#
MENTAL NOTE
Proof read before you send!
