3d text backwards when facing camera

I am new to this forum but have been using Unity for a while now. I have made alot of progress with the game I am working on so far but am having a hangup on this one piece.

 var Enemy: Transform;
 var distance = 5;
 var Explode : Transform;
 var circle : Transform;
 var projectile : Rigidbody;
 //sounds for attacking
 var SmiteSound: AudioClip;
 //background texture
 var attack : Texture2D;
 var smite : Texture2D;
 //textures for buttons
 var xout : Texture2D;
 var wasClicked: boolean = false;
 //arrow shooting
 var speed = 5.0;
 var rotateSpeed = 3.0;
 //health
 var DamageNumber : int; 
 var hp = 100.0;
 var HitPoints = 100.0;
 var ScorePoints = 2.0;
 var track_speed : float = 2;
 var look_at : Quaternion;
 var enemies_list = new GameObject[10];
 var aiming_at : int = 0;
 var aiming : boolean = false;
 
 var cameraToUse : Camera;
 var SetPlayerName : String;
 var TextMeshName : GameObject;
 
 var style : GUIStyle;
     
 //selection circle disabled
 circle.renderer.enabled = false;
 aiming = false;
 
 
 function Start(){
     style.normal.textColor = Color.yellow;
     style.fontSize = 15;
 
     DamageNumber = Random.Range(1,(HitPoints/6));
 }
 
 function OnMouseUp() {
     wasClicked = true; // turns on button.
     circle.renderer.enabled = true;
     
     if(aiming == false)
         {
         update_list();
         if (enemies_list.length > 0) // If we don't have enemies, we don't need to do the quaternion code
             aiming = false;    //  for performance reasons.
         }
 }
 
 function OnGUI() {
           
     GUI.depth = 50;
     if (wasClicked) {
         wasClicked=true;

                 instantiatedProjectile.velocity = (enemies_list[aiming_at].GetComponent(Transform).position - transform.position)*speed;
                 Physics.IgnoreCollision(instantiatedProjectile.collider, transform.root.collider);

                 wasClicked = false; // turns off button.

 @script RequireComponent(AudioSource)

This piece of code allows me to select the NPC, show the attack buttons, and calculate the death, then destroy and update scoring.

the problem is that the 3d text is backwards and not facing the camera. I did use the CameraFacingBillboard.cs example HERE and now the 3d text faces the camera as I walk around the NPC. However, the text is backwards and I cannot figure out how to flip it around. I am also using Unity 4 and a lot of the examples that I see are for Unity 3. Does this make a difference when doing the scripting?

the specific place the name of the NPC is placed is the first two lines of the update function.

 SetPlayerName = Enemy.name;
 TextMeshName.gameObject.GetComponent(TextMesh).text = SetPlayerName + "\n\r" + hp;

I have tried to do several examples and nothing seems to work, or breaks the code. Can anyone help?

Thanks.
