Error CS1525: Unexpected symbol `;', expecting `:'

I don't know where this error is coming from?

 Assets/track_creator.cs(19,32): error CS1525: Unexpected symbol `;', expecting `:'

This is my code:

 using UnityEngine;
 using System.Collections;

 public class track_creator : MonoBehaviour {
 public Vector3[] vertices;//my vertices
 public int[] triangles;//my triangles
 
 Quaternion startAngle;
 
 int distance;//length of vertices array
 Mesh mesh;
 
 void Start() {
     mesh = GetComponent<MeshFilter>().mesh;
     distance = mesh.vertices.Length;
 }
 
 public Vector3 calculateBezierPoint(float t, Vector3 p0, Vector3 p1, Vector3 p2, Vector3 p3) {
     float u = 1 – t;//19
     float tt = t * t;
     float uu = u * u;
     float uuu = uu * u;
     float ttt = tt * t;
 
     Vector3 p = uuu * p0; //first term
     p += 3 * uu * t * p1; //second term
     p += 3 * u * t * p2; //third term
     p += 3 * tttt * p3; //fourth term
     
     return p;
 }
 
 public void createPeice(GameObject track, Vector3 p1, Vector3 p2) {
     startAngle = transform.rotation;
     startAngle.z -= 90;
     
     
 }

}

I got the function from here: http://devmag.org.za/2011/04/05/bzier-curves-a-tutorial/

I haven't looked into it too much, but there seems to be nothing wrong with that line, and the one above it. I'm not too sure about multiplying p by floats, if that could be a problem too.
