Should not declare variable in view.h ?

Hi All,

I want to declare two variable, int x, and int y for coordinates.
When keyboard event happen, I will change this coordinates.

I add the declaration into View.h:
// Boki personal
    void Boki_updateXY(int x, int y);
    int boki_x;
    int boki_y;

and add a function for keydown events:

void Boki_updateXY(int x, int y)
{
    boki_x=x;
    boki_y=y;
}

but the error is:
 error C2065: 'boki_x' : undeclared identifier

Could you please advice?

Thank you very much!
Best regards,
Boki.
