Character moves off to side and floats

Hello again. I have used a script that has been very successful. Thanks to alucardj I now have a script that makes the character play the animations and move. Yet whenever I try to make the character move forward (by pressing the 'w' key) it moves off to the side and floats above the ground! Here is my script:

 #pragma strict
  
  
 var leftButton : String;
 var rightButton : String;
  
 var forward : Vector3;
 var dt : float; // double;
  
 var leftRotation : float;
 var rightRotation : float;
  
 var suspended : boolean;
 var moveSpeed : float; // double;
  
  
 function Start()
 {
 leftButton = "w";
 rightButton = "s";
  
 forward = Vector3.forward; // new Vector3( 0, 0, 1 );
 dt = Time.deltaTime;
  
 leftRotation = -0.7071069;
 rightRotation = 0.7071069;
  
 suspended = false;
 moveSpeed = 3.0;
 }
  
 function Update()
 {
 if ( suspended )
 {
 return;
 }
  
 //if (Input.GetButton(leftButton))
 else if ( Input.GetKey( leftButton ) )
 {
 transform.Translate( forward * moveSpeed * dt );
 animation.Play( "Walk_" );
 }
 //else if (Input.GetButton(rightButton))
 else if ( Input.GetKey( rightButton ) )
 {
 transform.Translate( forward * moveSpeed * dt );
 animation.Play( "Walk_" );
 }
 else
 {
 animation.Play( "Rest" );
 }
 }
  
 function SetSuspension( setting : boolean )
 {
 suspended = setting;
 }

Is there anything wrong with this script? I edited it a little and made it a little better, but nothing seems to be wrong except the fact that the character moves to the side and floats.
