Problem in Modeling Induction Motor

Problem in Modeling Induction Motor

I have to made an Induction Motor Model by myself and my first step was to just replicate an already existing example i.e. Electrical.Machines.Examples.AsynchronousInductionMachines.AIMC_DOL. Now I have replicated it but I can't parameterize the AIM_SquirrelCage because I can't set all the default values in it. Please see attachments. And help thanks.
