Method returning null, when referenced from another script

Hi, so in my 'Movement' script I have a method SetTarget(), that returns a string.

 public string SetTarget()
      {
          enemyTitles = new string[5] { "Hoplite", "Archer", "Cavalry", "Peltast", "Slinger"};
          if (target == null)
              Debug.Log("Obviously something has gone wrong, target is null!");
  
          if (Input.GetMouseButtonDown(1))
          {
              RaycastHit hit;
              Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
              foreach (string enemy in enemyTitles)
              {
                  if (Physics.Raycast(ray, out hit) && target != null)
                  {
                      target.transform.position = hit.point;
  
                      if (hit.transform.gameObject.tag == enemy)
                      {
                          enemySelected = true;
                          Debug.Log("engaging now." + enemy);
                         
                          return enemy;
  
                      }
                      else { enemySelected = false; }
                  }
              }
          }
          return null;
      }

Now, this is returned successfully: Debug.Log("engaging now." + enemy); Giving the correct and expected result. However, in my other script:

 private float Attack()
      {
  
          float finalAttackDamage = default(float);
          
          //I want different enemies to be dealt damage in accordance with their type. 
          if (move.SetTarget() == "Hoplite")
          {
              hoplite = GetComponent<Hoplite>();
  
              finalAttackDamage = hoplite.baseDamage;
              Debug.Log(finalAttackDamage);
  
          }
  
          if (move.SetTarget() == "Archer")
          {
              hoplite = GetComponent<Hoplite>();
  
              finalAttackDamage = hoplite.baseDamage + hoplite.counterArcher;
              return finalAttackDamage;
          }
  
          if (move.SetTarget() == "Peltast")
          {
              hoplite = GetComponent<Hoplite>();
  
              finalAttackDamage = hoplite.baseDamage + hoplite.counterPeltast;
              return finalAttackDamage;
          }
  
          if (move.SetTarget() == "Slinger")
          {
              hoplite = GetComponent<Hoplite>();
  
              finalAttackDamage = hoplite.baseDamage + hoplite.counterSlinger;
              return finalAttackDamage;
          }
  
          if (move.SetTarget() == "Cavalry")
          {
              hoplite = GetComponent<Hoplite>();
  
              finalAttackDamage = hoplite.baseDamage;
              return finalAttackDamage;
          }
  
         
  
          return 0.0f;
  
       }

move.SetTarget() is null. (I tested this earlier.) And I'm not sure why. I think I've referenced the script correctly:

  public Movement move;

Below the class. And the reference is filled within the inspector.

For whatever reason SetTarget = one thing in the Movement script, and null in my other script, when I try and reference it.

I'm also aware I write code very inefficiently, I'll make improvements once I get the script working.
