Weird error with member variables?

Ok, I'm stumped. I'm getting an access violation with the following
code, but no clue why.

Definition:
class CRoughView : public CScrollView
{
protected:
CRoughView();
DECLARE_DYNCREATE(CRoughView)
//...Overwritten functions...

public:
void SetStepDistance(float NodeStepDistance)
{
fDistance = NodeStepDistance;
}
private:
float fDistance;
};

Nothing to complicated right? A simple float variable, and a simple
variable assigment.

However, when I call the SetStepDistance function, I get an access
violation writing location 0x000002ac in debug mode. Anyone have any
clue why I'm unable to define / touch this variable?

Thanks,
Josh McFarlane
