Ethan controller rotation and collider problems on moving platform

hey, so I'm making this third person platform game which involves moving platforms. To this movable platform I have attached a script (seen below)which allows my character to be a parent of platform; which is duplicated so i can set one as a trigger raised 0.8 above the other. But whenever my character jumps on the platforms and i try to turn, it goes into the airborne animation stays like that: link text. Click the link to see the problem:

 ![using UnityEngine;
 using System.Collections;
 using System;
 
 public class StandPlaform : MonoBehaviour {
 
   
 
     void OnTriggerEnter(Collider col)
     {
     
         col.transform.parent = gameObject.transform;
     }
     void OnTriggerExit(Collider col)
     {
     
         col.transform.parent = null;
     }
 }][2]
