C/C++ :: Template Class With Error 2664

I'm trying to get the command pattern for template classes down. I'm just having a hard time implementing one part of the code. I can't figure out why both the method being passed and the type accepted are not the same type.

SimpleCommand class
template <class Receiver>
class SimpleCommand : public Command {
public:
typedef void(Receiver::*Action)();
SimpleCommand(Receiver *r, Action a) :

[code].....

And their instantiation

MyClass *receiver = new MyClass;
Command *aCommand =
new SimpleCommand<MyClass>(receiver, &MyClass::Action);
aCommand->Execute();
