Many thanks for the info and congrat for the working solution but unfortunately my one still doesn't work.
The same problem all the time doesn't matter what I set in the system.
I'm very frustrated at all, because I don't get any help except from you.
I have the same problem with the PayPal, too. If I use a discount I get an error message "The link you have used to enter the PayPal system contains an incorrectly formatted item amount."
It means that I wanna use two different type of payment methods without any success. It's a really bad rate for the VM, I guess...
Anyway, thanks for your help again. It's good to know that someone's eWay payment method just works well.
PS: I STILL NEED HELP
