Roll-A-Ball Tutorial public float speed

I am following the Roll-A-Ball tutorial, but the tutorials are outdated, being made for Unity 4.

After a massive amount of stress surrounding the rigidbody addforce, unity fixed the problem for me.

Now the tutorial is telling me add a speed factor (public float speed), but after returning to editor, there is no place to enter a speed value.

All Help appreciated.

Thanks

Update

Here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerController : MonoBehaviour
 {
     public float speed
 
     void FixedUpdate()
     {
         float moveHorizontal = Input.GetAxis("Horizontal");
         float moveVertical = Input.GetAxis("Vertical");
 
         Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
 
         GetComponent<Rigidbody>().AddForce(movement * speed * Time.deltaTime);
     }
 }

I also get the error in line 8 of:

PlayerController.cs(12,12): Error CS1519: Unexpected symbol `void' in class, struct, or interface member declaration (CS1519) (Assembly-CSharp)

Update 2

Thanks to LeftRight92 who pointed out the missing semicolon after public float speed.

New problem:

still don't have any driving force behind my ball, even after entering a value in the script 'speed' box

After entering any value, press play, but get no response.

As before, any help is great

Thanks Setho246
