Need Some Help With My Dialogue System

Hey guys I'm new with scripting in unity and i have a problem with the dialogue System I have been working on
the problem is in the Dialogue script according to unity

After the third sentence [when the CurrentLine variable = 3 and the WhereToSwitchPosition variable = 3] I'm getting an error that the "Array index is out of range.".
What does it mean and what can i do to fix this problem?

Dialogue Manager Script:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. public class DialogeManager : MonoBehaviour {
7.     public GameObject DialogeBox;
8.     public Text Text;
9.     public Text Continue;
10.     public Text TXTName;
11.     public bool DialogeActive;
12.     public string[] DialogeLines;
13.     public string Name;
14.     public int CurrentLine = 0;
15.     // Use this for initialization
16.     void Start () {
17.         DialogeBox.SetActive(false);
18.         DialogeBox.SetActive(false);
19.         CurrentLine = 0;
20.     }
21.  
22.     void Update()
23.     {
24.         if (DialogeActive && Input.GetKeyDown(KeyCode.Space))
25.         {
26.             CurrentLine++;
27.         }
28.         if(CurrentLine>=DialogeLines.Length)
29.         {
30.             DialogeBox.SetActive(false);
31.             DialogeActive = false;
32.             CurrentLine = 0;
33.         }
34.         Text.text = DialogeLines[CurrentLine];
35.         TXTName.text = Name;
36.     }
37.     public void ShowDialoge()
38.     {
39.         DialogeBox.SetActive(true);
40.         DialogeActive = true;
41.     }
42. }
43.  

Dialogue Script:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. public class Dialoge : MonoBehaviour{
6.     private DialogeManager DialogeManger;
7.     public int CurrentDialogeMember = 0;
8.     public int WhenToSwitchPosition = 0;
9.     public string[] Names;
10.     public int []WhereToSwitch;
11.     [TextArea(1, 10)]
12.     public string[] DialogeLines;
13.     public bool HaveSpoken = false;
14.     void Start()
15.     {
16.         DialogeManger = GameObject.FindObjectOfType<DialogeManager>();
17.     }
18.     void Update()
19.     {
20. if (DialogeManger.CurrentLine >= WhereToSwitch[WhenToSwitchPosition])
21.         {
22.             CurrentDialogeMember++;
23.             WhenToSwitchPosition++;
24.             DialogeManger.Name = Names[CurrentDialogeMember];
25.             DialogeManger.DialogeLines = DialogeLines;
26.         }
27.         else
28.         {
29.             DialogeManger.Name = Names[CurrentDialogeMember];
30.             DialogeManger.DialogeLines = DialogeLines;
31.         }
32.     }
33.     public void SendDialoge()
34.     {
35.         if (DialogeManger.DialogeActive == false)
36.         {
37.             if (HaveSpoken == false)
38.             {
39.                 DialogeManger.ShowDialoge();
40.                 HaveSpoken = true;
41.             }
42.         }
43.     }
44. }
45.  

DialogueTrigger Script:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. public class CollisionsDialogeTrigger : MonoBehaviour {
6.     public Dialoge DialogeToTrigger;
7.     // Use this for initialization
8.     void Start () {
9.    
10.     }
11.  
12.     // Update is called once per frame
13.     void Update () {
14.    
15.     }
16.     private void OnTriggerEnter2D(Collider2D collision)
17.     {
18.         if (collision.gameObject.name == "Camille")
19.         {
20.             DialogeToTrigger.SendDialoge();
21.         }
22.     }
23. }
24.  

 

ArrayIndexOutOfRange means you're trying to access an array element that doesn't exist.

Code (csharp):

1.  
2. int[] values = new int[10]; // 10 elements
3.  
4. values[67812983]; // error
5.  

So at some point, you're trying to access a dialogue or line of dialogue that doesn't exist.
