Right now, I'm getting 2 sizes on my page, one just says size and one has the months. Then when I tried to add to the cart, it says there's no such item combination... Also, need to clarify, each SKU has to be different right? I cannot have 2 SKUs the same?
Also for variants what do I do in the following scenario's
Scenario 1. I have the same product in 3 sizes (3-6 months, 6-9 months, 9-12 months), each size has a limited inventory of 100 should I choose the ""Variants having individual SKU/Price/weight/stock"" feature, and will I put the information as below:
Scenario 2: I have the same product in 2 different colors (grey and orange), each color has 3 different sizes, each size of each color has 50 in inventory
