I can not see variants or add to cart from the product list

[gabo28885]

Hi. My question is this: I'm using VM3 with "stockable CustomFields" plugin. I could create the product and its variants. The problem is that if the product has variants should go into detail to add to cart. What I need is that from the list to choose the variant and add it to the cart. Thank you very much.

PS: attached a picture where you can see the button "Elija una variante" deshabilidato and the button "Detalles de producto" that is if enabled.
