Raycast not ignoring layer

I asked this question before, but I edited it and for some reason it desapeared. I have a problem. I have a child object with a collider and the father is creating a ray. I need the father's ray to ignore this collider but it is not working. The ray starts from inside the childs collider, which I believe it might be the problem. I can't use the IgnoreRaycast layer because I need this child object to be picked up by other rays. I'm setting up the ray like this:

 void Start()
     {
         
         layer = LayerMask.NameToLayer("Touchable");
         mask = 1 << layer;
         
         mask = ~mask;
         
         //Initial Positioning
 
         yDir = mytransform.TransformDirection(Vector2.up) * rayCastRange;
         hitLocalDown = Physics2D.Raycast(mytransform.position, -yDir, rayCastRange, mask);
         
         if (hitLocalDown)
         {
             mytransform.position = hitLocalDown.point + hitLocalDown.normal * distancer;
             
         }
     }

I've read about this for a while and this should work, but it doesn't and I don't know why.

EDIT: I'm a moron, I had: mask = ~layer; insted of: mask = ~mask;

Now it works.
