Problems with includes/object of a different class as a private member

Instinct212 (2)
In trying to make a simple emergency room simulation I'm having some errors compiling. I want an array of PatientType objects as a private member of my ArrayType class where I initialize it in ArrayType's default constructor but I'm getting "In file included from errors" just by including ArrayType.h in it's .cpp and also in ArrayType.h it doesn't know what a PatientType object is.

To shorten the post I've removed several methods from ArrayType and most of main but I thought this would accomplish creating a new ArrayType object and adding a PatientType object to its array, still doesn't work =/
