'else' not working.... please help:(

Update:

your code is just flat out wrong. What are you trying to do? Input.GetAxis() returns a float between -1 and 1. So the comparison I wrote below fails because you have to compare floats to something.

Perhaps:

 if( Input.GetAxis("Vertical") >.5f && (Input.GetAxis("Horizontal") >0 )

but that may not do what you want.

old post

Everyone who answered (including me) this made typos.

This is your problem:

 if
     (Input.GetAxis("Vertical")) (Input.GetAxis("Horizontal"));

You have a semicolon at the end, but when you get rid of it, it's going to throw more errors.

Removing the semicolon:

 if (Input.GetAxis("Vertical")) (Input.GetAxis("Horizontal"))

Then, @insominx is correct, that's still bad syntax (but their answer has an extra paren too). If you mean to check if one OR the other, do this:

 if (Input.GetAxis("Vertical") || (Input.GetAxis("Horizontal") )

if you want to check to see if BOTH of them:

 if( Input.GetAxis("Vertical") && (Input.GetAxis("Horizontal") )

Notice the parentheses, Input.GetAxis() has one set of parens, the if statement has two.

 if
 (Input.GetAxis("$$anonymous$$ouse X")){
 yRot += 10 * Input.GetAxis("$$anonymous$$ouse X");
 }
 {
 transform.rotation = Quaternion.Euler(0, yRot, 0);
 }

On line 14 you have ended your If statement with a semicolon. The else therefore have no If to belong to. Remove the semicolon and you are good to go.

Line 13 and 14 look pretty odd:

 if (Input.GetAxis("Vertical")) (Input.GetAxis("Horizontal"));

Maybe you want somethign more like this:

 if (Input.GetAxis("Vertical") || Input.GetAxis("Horizontal")
 {
 ....
 }

As pointed out the code is full of holes. Here is a version that shouldn't throw errors, won't guarantee I've caught everything.

 #pragma strict
  
 var rotationSpeed : float = 10;
 var walkSpeed : float = 7;
 5.var gravity : float = 50;
 private var yRot : float;
  
 function Update () {
     var Controller : CharacterController = GetComponent(CharacterController);
     var vertical : Vector3 = transform.TransformDirection(Vector3.forward);
     var horizontal : Vector3 = transform.TransformDirection(Vector3.right);
  
     if (Input.GetAxis("Vertical") != 0 || Input.GetAxis("Horizontal") != 0) {
         animation.CrossFade("Run", 0.2);
         Controller.Move((vertical * (walkSpeed * Input.GetAxis("Vertical"))) * Time.deltaTime);
         Controller.Move((horizontal * (walkSpeed * Input.GetAxis("Horizontal"))) * Time.deltaTime);
     } else {
         animation.CrossFade("Idle", 0.2);
     }
  
     if (Input.GetAxis("Mouse X") != 0){
        yRot += 10 * Input.GetAxis("Mouse X");
        transform.rotation = Quaternion.Euler(0, yRot, 0);
     }
 }

My suggestion is to go to the beginner tutorials. You have a desperate need to understand the basics of scripting
