RemoteEvent change GUI text not working?

Ok, guys! I am trying to make an SCP game. I want to have the description change when the player clicks a button stating a role(Class-D, MTF, etc). Each button has a LocalScript. That script sends data to a RemoteEvent, which then sends the message to a Script that is supposed to change the text. But I keep getting an error! Please help me!

Hierarchy of GUI:

ServerScript:

local Title = script.Parent:FindFirstChild("TeamName")
local Desc = script.Parent:FindFirstChild("TeamDesc")
local Event = script.Parent.Parent:FindFirstChild("MakeTeam")
Event.OnServerEvent:Connect(function(title,desc)
    Title.Text = title
    Desc.Text = desc
end)

LocalScript:

script.Parent.MouseButton1Click:Connect(function()
    local Event = script.Parent.Parent.Parent.Parent:FindFirstChild("MakeTeam")
    Event:FireServer(script.Parent.Text,script.Parent:FindFirstChild("Desc").Value)
end)

The error I am getting:

19:48:41.078 - Players.TheLastHabanero.PlayerGui.ScreenGui.Desc.Script:5: bad argument #3 to 'Text' (string expected, got Object)

Thanks for any help!
