Hi!
I try to create our products (T-shirts) with different sizes and colors. When I click on Manage variants, I can see the listing of all the variants of the product. I cheked the value in a field of a variant but the next time I open the same product, the variants are still unchecked and with check-out is only the main product visible.
In other words: When I try to buy a red T-shirt, size XL, I get a blue one size L.

Hi
**It seem the default value of selected item from each list ( li) is use as a result instead the item the buyer select !!!

**the javascript for item value don't work . I test the hikashop demo + button to increment +1 item and it work !!
the increment don't work in Firefox and chrome ( only test in current browser version )

=> there must be a javacript code that avoid hikashop code to work ( order , version, syntax , too many javascript .framework ? )
I don't go to your co but think this ll help !! perhaps javascript syntax error for embedding javascript
