How do i make a Chat command that when u say a String Value it executes a script?

Rn im trying to make a bleach type game but i was just trying to make chat commands that will work but it isnt and i have no clue why

Script to make said values:

local service = game:GetService("DataStoreService")
local datastore = service:GetDataStore("Stats")
game.Players.PlayerAdded:Connect(function(player)
	print'Joined'
	local datafolder = Instance.new("Folder",player)
	datafolder.Name = "Data Folder"

	local fruitvalue = Instance.new("StringValue",datafolder)
	fruitvalue.Name = "KeyWord"
	local rad = math.random(1,2)
	if rad == 1 then
		fruitvalue.Value = "Unleash"
	elseif rad == 2 then
		fruitvalue.Value = "Go"
	end
	local dee = Instance.new("StringValue",datafolder)
	dee.Name = "Zanpakuto"
	local rad = math.random(1,2)
	if rad == 1 then
		dee.Value = "Zangetsu"
	elseif rad == 2 then
		dee.Value = "Sword"
	end
	wait(.1)
	if not player:WaitForChild'Data Folder' then return end
	print'loaded data folder'
end)

Chat command local script in starter player:

local plr = game.Players.LocalPlayer
local key = plr.Data.KeyWord.Value
local sword = plr.Data.Zanpakuto.Value
local debounce = false

plr.Chatted:Connect(function(msg)
	if msg == key..", "..sword then
		print("Shinkai")
	end
end)
