Product Variations – Pricing not updating on option selection

1. Price not updating: I’ve had a look at the page markup because this contains the parameters for every variation which WooCommerce thinks there are for this product, and that may not be the same as the variations which you think there are. There are 10 variations in the markup when there should be 3 x 3 = 9. In particular there is variation #96 which has no attributes set. The other 9 variations look correct.

If you look at the product page > Product Data section > Variation tab, you will see that each variation has an ID number. Can you see #96? If so, delete it. If not, then there is some corruption in the list of variations. If you are skilled with phpMyAdmin you could delete variation #96 from the database. If not, I think you need to remake the product page, then delete the old one.

I am hopeful that if this rogue variation is deleted the price will update properly.

2. Price range shown instead of lowest price: This is the default behaviour for WooCommerce, but you can alter what is displayed by using some custom css:

.price {visibility:hidden}
.price .amount:first-child {visibility:visible}

Anything more sophisticated will require some php coding.
