Spherecast if hit.distance <=, move the otherway

I’m writing a simple(!) script, where player is chased by an enemy. This enemy should never actually touch the player, and like a school playground game, if the player turns around or is about to collide with enemy, the enemy would run away.

However, it’s not quite working, I keep getting a warning in regards to the following line:

        if(hit.distance <= 5.0){

This is my entire update function:

function Update () {

    myTransform.rotation = Quaternion.Slerp(myTransform.rotation,Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
    myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

    var layerMask = 8;   
    var hit : RaycastHit;    
    var charCtrl : CharacterController = GetComponent(CharacterController);    
    var p1 : Vector3 = transform.position + charCtrl.center;

    if (Physics.SphereCast (p1, charCtrl.height / 2, transform.forward, hit, layerMask, 10.0)) {
        distanceToObstacle = hit.distance;
        if(hit.distance <= 5.0){  
            transform.Rotate(0,25,0);
        }
    }  
}

This my first experiment with SphereCast, so that could be the problem!

Thank you in advance!

The last two arguments for SphereCast are in the wrong order: they should be range and layerMask. Check also if the layer mask is ok, or remove this parameter - Unity will assume all layers by default.
