How to make a MPS that a player can upgrade?

Help

You can make a block that gives the player the current multiplier, but it would be better to use the property

What if..

if you’re using a trigger loop or a repeater, it triggers to several triggers. the triggers grant money. The triggers are only activated after you purchase the MPS upgrade. So like

Triggered → Trigger → Grant Money
The trigger is only activated on “MPSLv1”

Do the same thing for the rest.

Are these all the pictures?

You still need to use an item granter to grant the money each second (but it might be easier to use a property instead)
