How to create and display a list of enemies in upcoming wave?

Hi All,

I am working on a tower defense game, I wanted a way for the player to see the enemy units in the next wave,=. So my approach was to create a gui text object, add a refference to the waveManager(I just have it assigned in the inspector for now) class which holds all of the information for each wave. The waveManager class is broken down as a collection of events, and each even is broken down as a spawn events, which is where I set the enemy types and spawn locations. The spawn info is also a collection, so I have a list within a list. I get an argument out of range error, I know that I need to iterate over both the event and spawn infos collection, but I can't figure out how to do it correctly. Are there any examples on how to display the content in a wave?

 public class WaveManager : MonoBehaviour {
 
     public List<WaveEvent> events = new List<WaveEvent>();
     public List <Text> nextWaveText; //List of enemies
     private bool isPlaying = false;
     public float waveDelay = 5f; //Used to delay the stArt of eacach wave
 
 
     public void StartWave()
     {
             isPlaying = true;
 
             if (events.Count != 0)
         {
             events[0].StartEvent();
             for (int i = 0; i < events.Count; i++)
             {
                 Debug.Log(events[i].spawnInfos[0]);
                  //   nextWaveText[i].text = events[0].spawnInfos[i].spawnedEnemyName;
                 
                  
                     
             }
              
         }
               
             else
             {
                 LevelManager.Instance.Endwave();
       
 
             }
 
        
     }
 
    private void Update()
     {
         if (!isPlaying)
             return;
 
         if(!events[0].RunEvent())
         {
                 Debug.Log("End Event");
                 events.RemoveAt(0);
                 if (events.Count == 0)
                 {
                     LevelManager.Instance.Endwave();
                 }
                 else
                     events[0].StartEvent();
 
             }
         }
     }
