When I include the "program.h" header where the class is defined I get a "type redefinition" error.

public ref class clGlobals
{
public:
	double^ airDensity;
	double^ waterDensity;
	double^ gravitation;
};

clGlobals^ globals = gcnew clGlobals();
globals->airDensity = Convert::ToDouble(1.025);
globals->waterDensity = Convert::ToDouble(1025);
globals->gravitation = Convert::ToDouble(9.81);

double^ load = function1();

double^ load(clGlobals^ global);

double^ load(clGlobals^ global)
{
        // function stuff...
	return load;
}
