SYNCED Randomizer for avatars

I built the lucky block from super mario and its designed with 9 power ups, and a contact receiver for heads and fists to activate it. The problem is i havent figured out how to set up a proper randomizer that is synchronized for both the local user and other players.

I tried a float that changes in a looped animation, i tried an int that gets changed with the parameter driver on alternating states, and i even attempted using the islocal with no success.

Using the parameter driver random on a synced variable would also be the way I would go for, what isnt working with it?

If it’s the sync, are you sure the parameter you use is marked as synced, are you using any tool that makes stuff automatically for you?
