GUI Label/Text Area Doesn't Show Up Inside Scrollview

After I read some documents on how to make a simple scrollview and added some contents inside scrollview is quite straightforward and it worked. Now, I decided to add some GUI text or label to add this onto the scrollview. When I run it, it appears blank. Here's the code.

 void OnGUI() {
         scrollPosition = GUI.BeginScrollView(new Rect(0, (Adjust.getButtonSquare(false, true, 16)/2) - (Adjust.getButtonSquare(false, true, 14)/2), Adjust.getButtonSquare(true, false, 10), Adjust.getButtonSquare(false, true, 14)), scrollPosition, new Rect(0, Adjust.getButtonSquare(true, false, 10), 220, 1200));
         GUI.DrawTexture (new Rect(0, 0, 9999, 9999), guiTexture.texture);
         string text = GUI.TextArea(new Rect(10, 10, 209, 209),
             "Top-left \n" +
             "Top-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left " +
             "\nTop-left \n");
 //        text [0].transform.position = new Vector3 (0, 0, 0);
 //        GUI.Button(new Rect(120, 0, 100, 20), "Top-right");
 //        GUI.Button(new Rect(0, 180, 100, 20), "Bottom-left");
 //        GUI.Button(new Rect(120, 180, 100, 20), "Bottom-right");
         GUI.EndScrollView();
     }

UPDATE: By the way, if you're wondering where did I get this such code/method under Rect parameters and those are static return variables from Adjust.cs code. Here's the preview so you can understand its reference.

 using UnityEngine;
 using System.Collections;

     public static bool setToLandscapeStatic; // --> To be used for sharing reference.
     
     
     
     
 
     void Start() {
         setToLandscape = setToLandscapeStatic;
     }
     
     
     
     
 
     public static float GetButtonWidth() {
         if(setToLandscapeStatic) {
             return (Screen.width/16) * 7;
         } else {
             return (Screen.width/10) * 6;
         }
     }

         }
     }

         } else {

         }
     }
     
     
     
     
 
     public static float GetLocationY(float y) {
         if(setToLandscapeStatic) {

         } else {
             return (Screen.height/16) * y;
         }
     }
     
     
     
     
 
     public static float getButtonSquare(bool width, bool height, float value) {
         if(height) {
             return GUI.skin.button.fixedHeight = (Screen.height/16) * value;
         } else if(width) {
             return GUI.skin.button.fixedWidth = (Screen.width/10) * value;
         } else {
             return (Screen.height/16) * value;
         }
     }
     
     
     
     
 
     public static float getButtonSquare() {
         return (Screen.height/16) * 2;
     }
