[SOLVED] Trouble creating product combinations

[GoGoMo]

I'm trying to create a combination for a product I'm selling in my online store base on Quantity options:

 

1 Piece

Dozen (12 PCS)

Case (72 PCS)

 

but I get the following Alert: You can only add one combination per type of attribute when I try to add the Dozen (12 Pieces) after adding the first quantity attribute 1 Piece. How do I override this mention alert? What's an alternative work around to create the product combination I want for product I'm selling?

 

I want customers to be able to select from the specified Quantity options mentioned above from radio button attributes then they enter the exact quantity that they want to order in the quantity box then click Add to Cart button to add the specified quantity that they entered to the cart. I'm trying to do what this following seller is doing on their site; please see attach image thumbnail. Greatly appreciate some guidance.

 

 

[sOLVED] UPDATE: I figured out the issue I was having after watching Youtube tutorial by twetrain. I cannot add new combinations simultaneously in Prestashop v1.5.3.1 you have to add each new combination individually to a product and click Save and stay if you want to continue adding more combinations to same product or just click Save if you only have one new combination to add to a product. I hope my explanation helps anybody else that runs into the same problem later on.

Sorry to bump this old thread but this simply cannot work for me, as well as a lot of people... i need to add them all at once by simply using Ctrl key. No one has time to manually insert each value.

 

Please someone help me i loved the platform until i got to this point.
