Can´t get the character to Stay on a moving Platform

I Know that this Question have been asked alot of times... I have searched the web and tryed everything i could find on this topic, but still i cant get it working.

here are my Specs:

Character:

BoxCollider2D, Not set as an Trigger

RigidBody2d, is not kinematic

c# Code:

 using UnityEngine;
 using System.Collections;

     public float speedForce = 25f;

     public float playerSpeed;
     public bool goesWest;
     public float minSwipeDistY;
 
 
     public Transform grounder;
     public float radiuss;
     public LayerMask ground;
 
     Animator anim;
 
     //

                         transform.parent = hit.transform; 
                 } else {
