Which calculator are you using? There are several on the web, and different ones have different ways to enter the parents.
Cinnamon is a codominant mutant gene which is not present in a firefly. Cinnamon can be disregarded, unless the firefly's mate is a cinnamon or cinnamon combination.
If you are using the World of Ball Pythons calculator, it requires basic morphs. Their morph list says that firefly is the name for a combination of two basic morphs--fire and pastel. So fire and pastel are entered for the female instead of firefly.
Good luck.
