Not working

it’s not making any difference between fix amount or percentage.

when I add 15 fix amount, it goes 1500 EUR fee
when I add 15%, it still is 1500 EUR fee
when I add 9 EUR fix amount, it goes 900 EUR fee
…

Is it also possible to set a fee when order amount is LESS than x fix amount?
I want to add an administration fee for orders below a certain order amount.

Thanks!
