shipping rule error
I have a shipping rule where first item should be charged 10.50 and rest is charged 1.00
also if the shopping cart has a particular category "Category1" then shipping will be 12.50 each.
First Item is charged both 10.50 and 1.00
Category1 is charged both 12.50 and 1.00, Second quantity is charged 10.50, third is charged 1.00 and so on....
I am not sure what I did wrong
