Events example - beers in the fridge

Jul 31 2020 9:02 AM

Hi, i've been trying to understand the events. Could you please help me out with this little example I've created for myself?

There is a fridge filled with beers, a stuf can serve the beers. I would like the stuff be notified and disable from serving more when there is 0 beer in the fridge. But for some reason the example doesnt work.
