Error with Vector3 in Boo code

Code (Boo):

1. import UnityEngine
2.  
3. class NewBehaviourScript (MonoBehaviour):
4.  
5.     speed as double
6.  
7.     def FixedUpdate():
8.         moveHorizontal as double = Input.GetAxis("Horizontal")
9.         moveVertical as double = Input.GetAxis("Vertical")
10.  
11.         movement as Vector3 = Vector3(moveHorizontal,0,0,moveVertical)
12.  
13.         rigidbody.AddForce(movement * speed * Time.deltaTime)

I get this error:

Can somebody point out what I'm doing wrong? I'm trying to make ball roll on a playing field.

 

Probably needs something like:

Code (Boo):

1. movement as Vector3 = Vector3(moveHorizontal, 0, moveVertical)

 

Yes I was just experimenting with that but I was using a , as decimal point, thanks!
