Vector2 is always (0,0) - HELP

Hey, I'm working on a voxel engine and now I'm trying to set up a dynamic block texture uv system (just calculating the uv coords in anothe script). The problem is that when I define the Vector2 with the calculated variables it's still zero ( or (0,)) Here is some code:

 private function ApplyTexture(x, y, z){
     var xx : float;
     var yy : float;
 
     switch (voxelContainer[Vector3(x,y,z)]){
         case 1:

             xx = blocks.GetBlockCoordX(1, 1, 0);
             yy = blocks.GetBlockCoordY(1, 1, 0);
             uvs.Add(Vector2(xx, yy)); //This is always (0,0) but why?
             if(p){
                 print(xx); //This prints the right value which is 0.25
                 p = false;    
             }
             xx = blocks.GetBlockCoordX(0, 1, 0);
             yy = blocks.GetBlockCoordY(0, 1, 0);
             uvs.Add(Vector2(xx, yy));            //Same for the rest...
             xx = blocks.GetBlockCoordX(0, 0, 1);
             yy = blocks.GetBlockCoordY(0, 0, 1);
             uvs.Add(Vector2(xx, yy));
             xx = blocks.GetBlockCoordX(0, 0, 0);
             yy = blocks.GetBlockCoordY(0, 0, 0);
             uvs.Add(Vector2(xx, yy));           //...
 
             break;

This works because if I'm putting in the right values (0.25, 0.75 etc.) everything works fine but as soon as I use the variables it's messed up. Here is the GetBlockCoord() function:

 import System.Collections.Generic;
 
 var coords : List.<Vector2>; //I edit this in the inspector ...

 
 var texRes : float = 16;
 
 var blockWidht : float = 4;
 var blockHeight : float = 4; //...
 
 //For the X value...
 public function GetBlockCoordX(xOffset : float, yOffset : float, type : float) : float{
     var factor : float = 1 / texRes;
     var x : float;
     var y : float;
     x = (blockWidht*(coords[type].x)+xOffset*blockWidht) * factor;   //Well a bit messy but I get
     y = (blockHeight*(coords[type].x)+yOffset*blockHeight) * factor; //the right value from it.
     
     return x;
     
 }
 //For the Y value...
 public function GetBlockCoordY(xOffset : float, yOffset : float, type : float) : float{
     var factor : float = 1 / texRes;
     var x : float;
     var y : float;
     x = (blockWidht*(coords[type].x)+xOffset*blockWidht) * factor;
     y = (blockHeight*(coords[type].x)+yOffset*blockHeight) * factor;
     
     return y;
     
 }

What is wrong? Or is this some sort of bug? Help would be awesome! (Sorry for my bad english :P) Wizz
