can't delete with iptables

[Hideaki Nemoto <eme@xxxxxxxxxxxxxxxx>]

Hi,

I can't delete the rule by iptables, that I inserted
with my program using libiptc.

I've managed to insert, replace, and delete the rulesfrom my program.
But I can't delete that rule by iptables, or the ip6tables.

It tells me,

 "Bad rule (does a matching rule exist in that chain?)"

Could any one give me some clues to solve this problem?

I'll show the structure of my ipt_entry at the bottom.
Is there something wrong with this?Anything missing?
I've seen in a web site, that I need to build something about
matching if I wanted to delete the rule, but ipt_delete_num_entry
doesn't require that....

I'd really be happy for your help.

Thanks in advance.
