HUD object to attachment

I have a hud that needs to be picked up from the ground and then attached to the screen. I have two pieces. The first piece is the actual HUD that attaches, which is flat. I created a 3D non-functioning version of the HUD that is on the ground. I want the user to be able to touch the 3D HUD on the ground and have the 2d-functioning version to attach to their screen. Is there anyway to script this?

definatly use this in your 2d object, i imagin you touch the 3d on, a 2d one rezzes and then attaches <note> the attaching prim must be owned by the person wanting to attach it

key owner;

default
{
    state_entry()
    {
         owner = llGetOwner();
    }
    on_rez(integer r)
    {
        owner = llGetOwner();
        llRequestPermissions(owner,PERMISSION_ATTACH);
    }
    run_time_permissions(integer perm)
    {
        if(perm)
        {
            llAtachToAvatar(ATTACH_HUD_TOP_RIGHT);
        }
    }
}

theys are the attachment points you can use

ATTACH_HUD_CENTER_2
ATTACH_HUD_TOP_RIGHT
ATTACH_HUD_TOP_CENTER
ATTACH_HUD_TOP_LEFT
ATTACH_HUD_CENTER_1
ATTACH_HUD_BOTTOM_LEFT
ATTACH_HUD_BOTTOM
ATTACH_HUD_BOTTOM_RIGHT

Reminds me of a griefing object someone once tried. They made the original object for sell and on the change event of selling it attempted to attach.
