rpmrc: Topdir failed

Hello i have following simple rpmrc file in my home directory:

#############################################################
# Default values

topdir:/talladega/HUNI_2.0.1/HUNI/Agent/rpm

#############################################################

when i call

"rpm --showrc | grep -i topdir"


i get the error message :

" error: bad option 'toppdir' at /net/ec-n8200/data1/nsm-home/tgeelhaa/.rpmrc:4"


Can anyone help ?

I tried several type possibilities with and without spaces or tabs.

I tried also to pub the path in ""

im working under Linux 9.2 SUSE Professional, RPM version 4.1.1

Thanks Thorsten
