Simple LabVIEW Class Error

[TrapperDoo]

Im just trying to learn about classes.  Here is a simple program that is throwing an error on the class down-cast -

Why is this error happening?  The Parent-Child hierarchy is correct.  I created "Method 1.vi" of the Parent using the Dynamic Dispatch template and set it to "must override".  The child "Method 1.vi" is a VI for Override of the parent. version of Method 1.vi.

A Parent is not a Child.  So if you initialized as a Parent, you cannot downcast to a Child.  If you started with a Child, you can upcast to a Parent and later downcast to a Child.

I get it now.  Thanks for helping me.
