Why won't my property change gui work?

Hello, I'm trying to make a property change gui to easily change some properties of a part for a part of teaching my friends how to script, by observing the properties of a part and changing them. Can anyone help me fix this issue? Thanks! I know this script may be messy, I'm sorry, but I just made this script and I'm not sure where the issue is, it's not outputted. Once again, thank you!:

PartPropertyHandler (ServerScriptService):

local allowed = {"ISkyLordDoge"}

game.Players.PlayerAdded:Connect(function(player)
    for i, v in pairs(allowed) do
        if player.Name == v then
            script.SendProperties:Clone().Parent = player:WaitForChild("PlayerGui")
        end
    end
end)

game.ReplicatedStorage.ChangeProperties.OnServerEvent:Connect(function(player,BrickColorText,Material,Orientation,Position,Transparency)
    for i,v in pairs(allowed) do
        if player.Name == v then
            game.ReplicatedStorage.ChangeProperties:FireAllClients(BrickColorText,Material,Orientation,Position,Transparency)
            game.ReplicatedStorage.CanChange.Value = false
            wait(5)
            game.ReplicatedStorage.CanChange.Value = true
        end
    end
end)

Local Script (In the GUI):

local frame = script.Parent.Frame
local BrickColorText = frame.BrickColor.Text
local Material = frame.Material.Text
local Orientation = frame.Orientation.Text
local Position = frame.PositionE.Text
local Transparency = frame.TransparencyE.Text


script.Parent.Parent:WaitForChild("Toggle").MouseButton1Click:Connect(function()
    if script.Parent.Visible == true then
        script.Parent.Visible = false
    else
        script.Parent.Visible = true
    end
end)

local db = true
for i,property in pairs(script.Parent.Frame:GetChildren()) do
    if property.Changed then
        script.Parent.Submit.MouseButton1Click:Connect(function()
            if game.ReplicatedStorage.CanChange.Value == true and db == true then
                db = false
                game.ReplicatedStorage.ChangeProperties:FireServer(BrickColorText,Material,Orientation,Position,Transparency)
            else
                db = false
                script.Parent.Submit.Text = "Cannot send now"
                wait(2)
                db = true
                script.Parent.Submit.Text = "Send"
            end
        end)    
    end
end     

script.Parent.Cancel.MouseButton1Click:Connect(function()
    script.Parent.Visible = false   
end)

Local Script (In the part I'm trying to change the property of):

game.ReplicatedStorage.ChangeProperties.OnClientEvent:Connect(function(BrickColorText,Material,Orientation,Position,Transparency)
    local part = game.Workspace.PropertyPart
    part.BrickColor = BrickColor.new(tostring(BrickColorText))
    part.Material = Enum.Material.Material
    part.Orientation = Vector3.new(Orientation)
    part.Position = Vector3.new(Position)
    part.Transparency = Transparency
end)
