I've set up the attributes for size small and large and then created the variables (price,weight,dimensions) etc. I have the default variable set to not specified.
The problem I'm having is that the additional info does not appear on the product page in the shop, with the weight and dimensions.
I have left the weight and dimensions in the General Tab empty, because if I enter in say, the dimensions for size small there, that will only appear, and will not change when Large is selected from the dropdown menu in my shop.
I hope I'm making sense. Has anyone come across this before?
