Raycast and Update failure, help please.

// can anyone point out where my flaw is?

Assets/Script/Player.cs(39,34): error CS0201: Only assignment, call, increment, decrement, and new object expressions can be used as a statement.

void MakeMatch()
{
//Create Ray and RayCastHit variables, give the Ray an origin.
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;

if(Physics.Raycast (ray, out hit, 20))
{
Debug.DrawLine(ray.origin, hit.point, Color.red);

if(tileOne == null)
{
tileOne = hit.collider.gameObject;
}
else if(tileOne != null && hit.collider.gameObject != tileOne)
{
tileTwo = hit.collider.gameObject;
}
}
}


// Input trigger turn the blocks
void Update ()
{
if(Input.GetMouseButtonDown(0))
{
//Do something.
MakeMatch;
}
}

 

The compiler is simply trying to tell you: "What the hell am I supposed to do here?"
