The best way to use the calculator would be to click on the link at the top where it says "My corn snake isn't here. What do I do?" It will give you the genetic makeup of most of the trade-names. For your anery, you would obviously want to click on the Anerythristic under male or female (depending on who is what) and for your Avalanche, you'd select Amel, Anery, and Diffused according to the link I spoke of above. Once those are in, just click Calculate and they will show you both the pheno and genotypes of the babies that are possible.
