I'll sell fabrics and want to be able to sell quantities by decimeter based on a price /meter (basicly, price is 10 euro for 1 meter, minimum to order is 0,1 dm) I modified the code  according to what I found here in the forum so that I can purchase an article for 1.5 in quantity, but the price is still going as 1, and if I order 0.5 I get an error message that says my basket is empty. Does anyone know if you can change this in any way?
