What's wrong with this simple script?

Right now i get the this error when pressing the play button:

-Assets/Movement new.js(2,14): UCE0001: ';' expected. Insert a semicolon at the end.

This is the Script:

---

using UnityEngine.Transform;

 function Start () {
     
 }
 
 function Update () {
     if (Input.GetButton("Forward"))
     Transform.Translate(Vector3.forward);
 }

---

when i put a ; after the identifier "using" like Unity tells me to. (Which would make no sence.) I get the following errors:

-Assets/Movement new.js(9,27): BCE0020: An instance of type 'UnityEngine.Transform' is required to access non static member 'Translate'.

-Assets/Movement new.js(1,1): BCE0005: Unknown identifier: 'using'.

-Assets/Movement new.js(1,20): BCE0034: Expressions in statements must only be executed for their side-effects.

---

So i can't figure out whats wrong, i just started scripting, and i believe everything in there is right. (Although i am appearantly horribly wrong. If there is something wrong with it please tell me, it's kinda really bugging me.

EDIT: thanks everyone, it's now fixed, but now i have another problem, i added some stuff, and now it gives me an error about a non-existant line, how can i solve this?

Updated script:

---

import UnityEngine.Transform;

function Start () {

}

function Update () { if (Input.GetButton("Move Forwards")) transform.Translate(Vector3.forward);

 {
     if (Input.GetButton("Move Backwards"))
     transform.Translate(-Vector3.forward);
 }

---

Accompanied By the error: Assets/Movement new.js(16,1): BCE0044: expecting }, found ''.

That's what i find weird, since there is no sixteenth line. This happend to my previous scripts as well, making them all unuseable.

EDIT2: Nevermind, i managed to fix it.
