3 dependent attribute

3 dependent attribute

Good evening.
We shop safety signs. Each item in our store has two attributes is the "size" and "material"
There was a task to specify the quantity of goods that is the minimum order In attributes require add-dependent field to the existing two, which will display the minimum order quantity for the chosen size of the sign.
The problem occurs when you connect the three attributes. When I chose three attributes and click Add message "Failed to add the attribute."
Is it possible to merge the three attribute?
Or the decision can be arranged in another way?
