What you did was halfway there. Your code was correct, but it only retrieved the parameter, it didn't tell the code what to do with it. I've added some extra code now which should make it work. See. I had to add an extra line for the nominative singular form, because by default, the nominative singular is taken from the strong singular stem (the one named "sg" in the code). The "nom_sg or ..." bit tells it to use the nom_sg form, if it was given, otherwise use whatever comes after.
