Hi, Nicolas. I am having a similar issue. My client sells fabric. She wants one price field with yards (which has an unlimited amount of yards) and one finite field that is for 1/4, 1/2 and 3/4 yards. So the yard field the client fills in with any quantity, but the "1/4, 1/2 and 3/4 yards" field is a drop down box.
If I create variants, that creates a number of problems. 1) When the client chooses 10 yards, it increases the ""1/4, 1/2 and 3/4 yards" field as well. This field would always be 1; only the yards should be multiplied by the quantity. 2) If I do variants, there is no limit to the number of yards someone can buy so there is no end to the variants. Besides, there are hundreds of fabrics and hundreds of variants. I tried duplicating a product and using the percentage field, but all of the variants reset for the duplicated product!
Any ideas? I am not a coder so if there is some Hikashop manipulation, is there a fee to get someone to do that few lines of code for me?
Thanks
