Why isn't this skript working?

[Nd_]

So I added a code to prevent people from losing hunger. The problem is, it doesn't work. There is no error message when I refresh it. Please help.

Thanks

Code:

on food bar change:
 feed the player by 1 beef

What you can also do is instead do "set player's hunger meter to 10"
