Help Problem Sinc Server Client

Hi everyone,

I'm here to ask for help with a problem I just can't seem to solve.

For weeks, I've been trying to make it so that a value, like "hello" for player 1, can be read by player 2. I’ve tried using NBT and other methods. Everything works fine locally, but it doesn’t work on the server.

What can I use to solve this issue? Keep in mind that each player will have their own value, and everyone should be able to read it.

Thanks in advance!
