problem with random array

Hi,

For some reason that i cannot fathom for myself, or fix by searching, the below code does not seem to be getting an array from the 4 in the list. The text in the GUI Label works fine and i get no errors in the console when i play it, but after the line "Edison Utd Vs. " then it is just blank, and doesnt appear to be choosing a random name.

If anyone could explain this to me, without telling me to seach google then i would be very grateful. Everything i have found on google is alot more complex than this and doesnt really give me the answer i am looking for.

Many Thanks in advance.

         public var NameArray : String[] = ["Rugeley","Lichfield","Cannock","Stafford"];
         var chosenName : String;
         
     function ChooseName()
         {
             chosenName = NameArray[Random.Range(1,NameArray.length)];
         }
     
     function OnGUI() 
         {
            GUI.Label (Rect (10, 30, 100, 100),"Edison Utd \n Vs \n " + chosenName);
         }
