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)
