knockback player along the Y-axis

I don't think the Y-axis for my code is working. Iv'e tried increasing the yForceToAdd and the localScale.y but (when I collide with the object that has this script attached to it) my player only goes (when I collide at the top of the object) X=1, Y=1 or X=-1, Y=1 and not X=0, Y=1 as well. the same problem with the bottom of my object X=0, Y=-1 doesn't seem to work either. can someone help with this problem? so basically:

1. when player collides with object, player should get knock back

2. depending on where the player hits I want the script to calculate the player's direction when it bounces off the object

3. The script does that, but the Y-axis is not working properly

4. when the player hits the center of the objects box collider the player is sent of diagonally not straight forward

5. I want (when my player hit the center on the box collider) my player to go straight forward.

      //Store the vector 2 of the location where the initial hit happened;
   
        Vector2 initialHitPoint = new Vector2 (other.gameObject.transform.position.x, other.gameObject.transform.position.y);
   
          float xForce = 0;
   
          float yForce = 0;
   
         //Grab our collided with objects rigibody
   
         Rigidbody2D rigidForForce = other.gameObject.GetComponent<Rigidbody2D>();
   
         //Determine left right center of X hit
   
       if (initialHitPoint.x > (this.transform.position.x + (this.transform.localScale.x /3)))
   
       {
   
          xForce = 1;
   
        }
   
       else if (initialHitPoint.x < (this.transform.position.x - (this.transform.localScale.x /3)))

          { 
   
          yForce = 0;
   
           }
   
        rigidForForce.velocity = new Vector2(xForce * xForceToAdd, yForce * yForceToAdd);
