Bullet shooting DOWN and not forward?

Hello Unity pros ;)

I have a problem, when I "Instantiate" a bullet and then add force to it in the Z direction, it shoots DOWNWARDS. I am experienced with Unity 3d and my scripting knowledge is not a problem:

var speed = 10.0;

function Start ()
{
transform.Translate(Vector3.forward * speed * Time.deltaTime);
}

This script should make it go forward in the forward direction, but it shoots DOWNWARDS. Do you know a way to fix it because Iam blank.

Thank you :)

"Forward" is relative; rotate it 90 degrees.
