Solved SOLVED PREFIX SKRIPT

[Sweball77]

Don't worry I solved it now
Here's the skript if you guys also wanna use it:

command /prefix <text>:
trigger:
set {Prefix::%player's uuid%} to colored arg-1

on chat:
set {_message} to message
set {_player} to player
set {_color} to {Color::%player's uuid%}
set {_prefix} to {Prefix::%player's uuid%}
replace all "&" with "§" in {Prefix::%player's uuid%}
cancel event
message "%{_prefix}% %{_player}%: %{_message}%" to all players

I dont think you need to replace &.
Also making a chat thing should be as simple as

on chat:
  set chat format to "%{prefix::%player's uuid%}% %player's display name%: %{color::%player's uuid%}%%message%"

I tried without using the replace thing and it didn't work and therefore if you'd not add the replace thing and all of that it wouldn't work
