Say i have objects A, B, C, D, 1, 2, and 3. How would you code it to where there's a mix verb. When activated a list will pop up, showing the objects you have. You can choose one. And another one will pop up and say mix it with... And the list will show what you now have left besides what you chose in the last list. And have the out come like this.

object 1 + object 1 = object A
object 1 + object 2 = object B
object 1 + object 3 = object C
object 3 + object 3 = object D

The names are just substitutes for real names.
Can you help. Can you even understand all that mess up there( it was hard to put in words.)
