PRIM_BUMP_SHINY hows that work

Never have seen a good example of this how do you set a primitives shiny. I don't want to set the bump to anything just be able to set the shiny on off
tried using

default
{
    state_entry()
    {
         llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE, PRIM_SHINY_MEDIUM]);
    }

    touch_start(integer total_number)
    {
        llSetPrimitiveParams([ PRIM_BUMP_SHINY,  PRIM_SHINY_NONE,
    PRIM_BUMP_NONE, PRIM_SHINY_NONE]);
    llSleep(5);
     llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE,PRIM_SHINY_HIGH]);
    llSleep(5);
          llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE, PRIM_SHINY_NONE]);
    llSleep(5);
     llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE,PRIM_SHINY_HIGH]);
    llSleep(5);
        llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE, PRIM_SHINY_NONE]);
    llSleep(5);
     llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE,PRIM_SHINY_HIGH]);
    llSleep(5);
        
    }
}

and rearanged these into many different orders only seems to be changing the bump to wood.

I think that your parameters in the wrong order...

instead of this:

         llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_BUMP_NONE, PRIM_SHINY_MEDIUM]);

try this:

         llSetPrimitiveParams([ PRIM_BUMP_SHINY, ALL_SIDES,
    PRIM_SHINY_MEDIUM, PRIM_BUMP_NONE]);
