Iv been working on a simple dialog system only form some reason the next line in the conversation wont come up.
I think its something to do with me trying to use GUI labels.
Here is the code:

public class NPC_Dialog_2 : MonoBehaviour {

public string[] questionsButtons;
public string[] answerButtons;
bool Dialog = false;
bool Quest = false;

void OnGUI () {
	GUILayout.BeginArea(new Rect(700,600,400,400));
	
if(Dialog)
	{
		Disable_Mouse();
		
		GUILayout.Label(questionsButtons[0]);
		
			if(GUILayout.Button(answerButtons[0]))
			{
				GUILayout.Label(questionsButtons[1]);
			
				if(GUILayout.Button(answerButtons[3]))
				{
					GUILayout.Label(questionsButtons[3]);
					Dialog = false;
					Enable_Mouse();
				}
			}
		
			if(GUILayout.Button(answerButtons[1]))
			{
				GUILayout.Label(questionsButtons[2]);
				Dialog = false;
				Enable_Mouse();
			}

	}
		
	GUILayout.EndArea();
	}

void OnTriggerEnter () {
	Dialog = true;
	Disable_Mouse();
}

void OnTriggerExit () {
	Dialog = false;
	Enable_Mouse();
}

A GUI Button only returns true at the time it was clicked and the executes the code from there. OnGUI is called I think twice per frame; The label probably is getting displayed for a nano second and when OnGUI is called again your button is now false, the label will not show.

You need to track the state of which buttons have been clicked.
