Variables defined in editor, but clear on runtime

OK, so I have a GUI script, which gets a variable called BarkyStatus, which is a script name. The GameObject that has that script is the player, which I define. But, whenever I hit Play, the variable clears and halts the entire script.

Here is the basic formula:

• Script needs the BarkyStatus variable, which contains score data, pickup data and health data.

 var scoreTexture : Texture;
 var timeTexture : Texture;
 var checkmarksTexture : Texture;
 var gemsTexture : Texture;
 var healthBase : Texture;
 var healthBar : Texture;
 
 var nativeVerticalResolution = 600.0;
 
 var barky : BarkyStatus;
 barky = GetComponent("BarkyStatus");
 
 function OnGUI () {
     var timeText = Time.timeSinceLevelLoad;
     GUI.matrix = Matrix4x4.TRS (Vector3(0, 0, 0), Quaternion.identity, Vector3 (Screen.height / nativeVerticalResolution, Screen.height / nativeVerticalResolution, 1)); 
 GUI.DrawTexture(Rect(5,5,80,20),scoreTexture,ScaleMode.ScaleAndCrop,true,0);
 GUI.Label (Rect(85,6,100,23), barky.score.ToString());
 GUI.Label (Rect(65,27,100,23), timeText.ToString());
 }

Well, that's the incomplete version, anyway.

• Plug in the variable in the editor.

• Press Play, and the variable clears itself.

Any tips on how to prevent this? Not that this affects the core gameplay, but I kinda want to see what my score is during gameplay. Help?
