BCE0019: 'Add' is not a member of 'UnityEngine.Transform[]'

I need help with a problem I get in my code. I am writing a code to generate a maze using Prim's Algorithm. This is the code I get the error on: function SetAdjacents() { var x : int; var y : int; for(x = 0; x < size.x; x++) { for(y = 0; y < size.y; y++) { var cell : Transform; cell = grid[x,y]; var cScript : CellScript = cell.GetComponent(CellScript); if(x - 1 >= 0) { cScript.adjacents.Add(grid[x-1,y]); } if(x + 1 < size.x) { cScript.adjacents.Add(grid[x+1,y]); } if(y - 1 >= 0) { cScript.adjacents.Add(grid[x,y-1]); } if(y + 1 < size.y) { cScript.adjacents.Add(grid[x,y+1]); } } } }

I get the error on all the lines of codes that say cScript.adjacents.Add(etc.) The cScript that I take the variable adjacents is here:

 #pragma strict
 
 var adjacents : Transform[];
 var position : Vector2;
 var weightCell : int;
 
 function Start () {
 
 }
 
 function Update () {
 
 }

I haven't done much with the second script. Thanks for your help!
