Ok, so let’s have product : Product X
Product X have 2 attributes : Size (S, M, L) and Tape Width(15mm, 20mm, 25mm)
And now we create variants for them and the price looks as follows. S: $10, M:$15, L:$20. The width of the tape does not affect the price.
(For Woocomerce attributes I use plugin “Variation Swatches for WooCommerce” by Cart Flows)
And now as I test for myself, changing the size shows the sum of the price, but when I change the width of the tape this price disappears. As I have shown in the earlier screenshots
My shop is not published yet. Can I show you this issue in other way?
