Having a player move around a 48 step game board that's circular using a 1d6 and waypoints?

I'm new to unity. I designed a tarot board game that I want to make into an app. I made a basic waypoint manager but I'm having trouble getting the dice to work with the players movement along the board. I know I'm missing some code but I've been searching the web for more info but board game development is scarce at best. How do I get a 1d6 to control my players movement around the board? Any help is greatly appreciated. Here's what i have so far not so good...

using UnityEngine; using System.Collections;

public class BoardgameMovement : MonoBehaviour

{

 public Transform target;
 public int Die_d6=1; 
 public int Waypoints=0; 
 bool test= true; 

 void Update () 
 { 
     if (test == true) { 
         Die_d6= 2; // the total value of the dice 
         test = false; 
     }
     
     Waypoints = Die_d6; // how many movements remaining
     
     // while the player can move
     while (Waypoints < 0) { 
         Waypoints = (Waypoints + 1);
             
     } 
 }

}
