eal newb ie - cannot call a functio

Hey, can you use code tags please? Using code tags properly

Function getfromurl isn’t static, so you can’t access to it like that, you need instance or static method.
Istance is like that:

public class TestScript : MonoBehaviour
{
// instance - drag in inspector or find gameobject with it in awake/start
    public internetz internetzInstance;

// Use this for initialization
void Start ()
{
    Console.WriteLine("debugg ");
    string t;
    t = internetz.getfromurl("");
}
