Hi everybody sorry for my poor english.

My script doesn't work very well

I want to share bandwidth between 3 subnet (64k, 128k, 256k)
if i put the flag bounded on the class root that's doesn't work bandwidth is not limited
if i put the flag bounded on each class, all the subnet is limited by each rule:

subnet 64 can't use more than a total of 64k as it was 1 single user
...

so i don't know how to share 64k by user on subnet 64, 128k by user on subnet 128, 256k by user on subnet 254.

What's wrong with my script?

thx a lot.
Michael
