SuSEfirewall2 errors on SuSE linux 8.1

Hi there! On my SuSE Linux 8.1 professional box I configured the firewall and when I run SuSEfirewall2 I receive this kind of message: /sbin/SuSEfirewall2: line 696: test: 10.10.0.0/16: integer expression expected /sbin/SuSEfirewall2: line 696: test: 10.10.0.0/16: integer expression expected /sbin/SuSEfirewall2: line 696: test: 10.10.0.0/16: integer expression expected /sbin/SuSEfirewall2: line 696: test: 10.10.0.0/16: integer expression expected iptables v1.2.7a: Maximum prefix length 29 for --log-prefix Please, what does it mean? My firewall configuration is attached. Thanks Fiorenza <<SuSEfirewall2>>
