[unanswered]why won't this script change values in the localplayer?

why won't this script change values in the localplayer? Another script makes the values, I checked it and they are there. The script is a local script in a tool. the toolt is the tool. the value tool is in the player. it is not the tool itself.

local plyr = game.Players.LocalPlayer
local Toolt = script.Parent

Toolt.Equipped:connect(function(mouse)
    plyr.Tool.Value = "Test"
    plyr.Tool.Ammo.Value = 20
    plyr.Tool.Clip.Value = 100
end)

Toolt.Unequipped:connect(function(mouse)
    plyr.Tool.Value = "Hands"
    plyr.Tool.Ammo.Value = 0
    plyr.Tool.Clip.Value = 0
end)
