Thread: static member variable

Hello

I have a static member variable "total" and I want to use it inside this class.
Can somebody explain me why this doesn't work?

Code:

#include "Artikel.h"

class WinkelCar {


	public:

		void add(int index, Artikel *object);
		void ShowCar();
		
	private:
		Artikel *array[2];
		static int total;

};

int WinkelCar::total = 0;

If i compile this, I get this error:

Code:

ld: duplicate symbol WinkelCar::total      in /var/folders/LO/LOQvxAvTExyhCT-wRaKGYU+++TI/-Tmp-//ccH9KXCA.o and /var/folders/LO/LOQvxAvTExyhCT-wRaKGYU+++TI/-Tmp-//ccObRT7c.o
collect2: ld returned 1 exit status

Thank you very much

ty that was the error
