How can I overload a constructor in a private nested class without getting a "Resource Not Found" error when I call Inherited Create?

I have a Managed Record named TEmail with a nested private class called TEmailForm that inherits from TForm. The idea is my email Record can create a modal form as needed for the user to type an email. I need the TEmailForm to have a reference to the TEmail Record that created it, so I overloaded the constructor for my nested EmailForm class like this:

constructor Create(AOwner: TComponent; EmailPnt: PEmail); reintroduce;

EmailPnt: PEmail is a pointer to the TEmail Record that created the form.

I then implemented my constructor like this:

constructor TEmail.EmailForm.Create(AOwner: TComponent; EmailPnt: PEmail);
begin
    inherited Create(AOwner);
    Email := EmailPnt;
end;

It compiles fine, but when I get to the line that says inherited Create(AOwner);, I get the following exception:

Project EmailTester.exe raised exception class EResNotFound with message 'Resource TEmail.TEmailForm not found'.

If I move the TEmailForm class outside of the TEmail Record so it is no longer a private nested class, everything works perfectly, but I don't want the TEmailForm exposed publicly when you use the Unit. What can I do here to get this to work?
