3-6 3-6m 6-9 9-12 button cart changed clarify code color colors combination copy correct descriptive feature grey individual information inventory item limited months options or3-6m orange page price product scenario six size sizes sku sku1 skus stock unique variants weight

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:

productSKU,10,5,100,3-6 months
productSKU,10,5,100,6-9 months
productSKU,10,5,100,9-12 months

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

productSKU,10,5,50,grey,3-6 months
productSKU,10,5,50,grey,6-9 months
productSKU,10,5,50,grey,9-12 months
productSKU,10,5,50,orange,3-6 months
productSKU,10,5,50,orange,6-9 months
productSKU,10,5,50,orange,9-12 months

That will only happen if you had all the SKUs same or if you changed options and did not copy the new button code Correct. SKUs have to be unique.

For Scenario 1
Yes, you will need to choose "Variants having individual SKU/Price/weight/stock" feature

The information you put is correct except all three SKUs should be different like SKU1, SKU2 or SKU3 or if you want it to be more descriptive use 3-6M,6-9M,9-12M

For Scenario 2

The information is correct except all six SKUs should be different like GR3-6M, GR6-9M,
GR9-12M, OR3-6M, OR6-9M, OR9-12M
