My Slider GameObject has a GUIText child. I am writing a C# script that should change the text component in the GUIText, but instead of this I am getting:

***error CS1061: Type `UnityEngine.GUIText[]' does not contain a definition for `text' and no extension method `text' of type `UnityEngine.GUIText[]' could be found (are you missing a using directive or an assembly reference?)***

 public Slider timeSlider;
 int i = 5;

 timeSlider.GetComponentsInChildren<GUIText>().text = 'Some Text' + i;
 //timeSlider.transform.GetComponentsInChildren<GUIText>().text = 'Some Text' + i; // doesn't work either

From the documentation I understand that GUIText should have a 'text' variable - Would anyone know why <GUIText>().text is invalid?

Thank you!
