Resolved "}" and ";" Error

Hi, I dont know whats wrong with my unity but when i added to my script a Particle Stop/Play says there´s a ";" and a "}"
Im new at this but im pretty sure im not missing anything!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Wheel_Movement : MonoBehaviour
6. {
7.     AudioSource EngineSound;
8.  
9.     CircleCollider2D WheelContact;
10.  
11.     public HingeJoint2D backwheel;
12.  
13.     public ParticleSystem Particletest;
14.  
15.     JointMotor2D motorBack;
16.  
17.     JointMotor2D motorFront;  
18.  
19.     public float BackSpeed;
20.     public float FrontSpeed;
21.  
22.     public float torqueB;
23.     public float torquef;
24.    
25.     public bool TractionBack = true;
26.  
27.  
28.  
29.     void Start()
30.     {
31.        
32.     }
33.  
34.     void Update() {
35.         if (Input.GetAxisRaw("Vertical") > 0) {
36.  
37.             if (Input.GetKeyDown(KeyCode.W))
38.             {
39.                 EngineSound.Play();
40.  
41.                 if (Input.GetKeyUp(KeyCode.W))
42.                 {
43.                     EngineSound.Stop();
44.                     play (Input.GetKeyUp(KeyCode.W))
45.                     {
46.                         Particletest.enableEmission = true;
47.                     }
48.                     else if (Input.GetKeyUp(KeyCode.W))
49.                     {
50.                         Particletest.enableEmission = false;
51.                     }
52.                 }
53.             }
54.  
55.             if (TractionBack)
56.             {
57.                 motorBack.motorSpeed = FrontSpeed * -1;
58.                 motorBack.maxMotorTorque = torquef;
59.                 backwheel.motor = motorBack;
60.             }
61.  
62.  
63.         } else if (Input.GetAxisRaw("Vertical") < 0)
64.         {
65.  
66.  
67.             if (TractionBack)
68.             {
69.                 motorBack.motorSpeed = BackSpeed * -1;
70.                 motorBack.maxMotorTorque = torqueB;
71.                 backwheel.motor = motorBack;
72.             }
73.  
74.  
75.         } else {
76.  
77.             backwheel.useMotor = false;
78.         }
79.    
80.     }
81. }

 

The error says you missed semicolon at the end of line 44, but I guess there should be

if

instead of

play

at the beginning of same line.
the error message contains the line number that generates error by the way.

 

Thanks man but, i forgot to put it as resolved im sorry but thanks!
