touches and OnGUI crash

When i touching the RepeatButton
and i use the second finger touched then the RepeatButton Cancelled
how can i fix it.

if (Input.touchCount == 2)
{
if (Input.touches[0].phase == TouchPhase.Moved)
{
return ;
}
if (Input.touches[1].phase == TouchPhase.Moved)
{
float mx = Input.touches[1].deltaPosition.x * m_speed;
float my = Input.touches[1].deltaPosition.y * m_speed;
boy.transform.eulerAngles = new Vector3(boy .transform.eulerAngles.x,boy.transform.eulerAngles.y-mx, boy.transform.eulerAngles.z );
Camera.main.transform.eulerAngles = new Vector3(Camera.main.transform.eulerAngles.x +my ,Camera.main.transform.eulerAngles.y , Camera.main.transform.eulerAngles.z);

}
}
