Making GUIText appear and disappear

What I am trying to do is I have a camera with three GUITextures. I am turning all of them into buttons. I have my back button GUITexture working, but I've run into a problem with the other two. When I click one of the two buttons I want both to deactivate and be replaced with a a GUIText that appears in between them. The problem is that when I click, the Text appears momentarily and then disappears while the Textures deactivate momentarily and then return. How do I make the Text stay even after I am done clicking and the Textures to stay deactivated? Any thoughts are appreciated!

Here is the code that I am using:

 using UnityEngine;
 using System.Collections;
 
 public class LegZoom2 : MonoBehaviour {
 
     public GameObject body;
     public GameObject player;
     public GameObject legcamera;
     public GUITexture backbutton;
     public GUITexture simtest;
     public GUITexture simpract;
     public GUIText simtext;
 
     // Use this for initialization
     void Start () 
     {
         Screen.showCursor = true;
     }
     
     
     // Update is called once per frame
     void Update () 
     {
     
         Vector3 StartPos = legcamera.transform.position;
         Vector3 EndPos = new Vector3 (6.1f, 9.1f, -4.017f);
     
         
     if(((body.transform.position.x)-(player.transform.position.x)) <= 2.6f && (((body.transform.position.z)-(player.transform.position.z)) >= -1f||((body.transform.position.z)-(player.transform.position.z)) <=3.4f)) {
         
         legcamera.SetActive(true);
         simtext.enabled = (false);
         simtest.enabled = true;
         simpract.enabled = true;
         player.GetComponent<AudioSource>().enabled = false;
         legcamera.transform.position = Vector3.Lerp (StartPos, EndPos, Time.deltaTime * 2);
         //camera.transform.position = new Vector3 (6, 9.2f,-4f);
         }
         
     else {
             legcamera.SetActive(false);
             legcamera.transform.position = new Vector3(4.54f, 9.434f, -3.932f);
         }
             
         if (simtest.HitTest(Input.mousePosition) && Input.GetMouseButtonUp(0)){
             
             simtext.enabled = true;
             simtest.enabled = false;
             simpract.enabled = false;
         }
         }    
     }
