Custom chat function not working?

Hi, I'm currently testing a prototype for a custom chat using a text box, scripts and a text label. It doesn't display a error, but when I press enter, the script doesn't work and the text doesn't appear. I am currently on my MacBook, so I can't show any gifs but here's the scripts.

LocalScript:

local userInput = game:GetService("UserInputService")

userInput.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.Return then
        if script.Parent.TextBox.Text == "" then
        else
            local text = script.Parent.TextBox.Text
            game.ReplicatedStorage.chatFunction:FireServer(text)
            script.Parent.TextBox.Text = ""
        end
    end
end)

Script:

local function Chat(text)
    local CloneText = script.Parent.TextLabel:Clone()
    CloneText.Visible = true
    CloneText.Text = text
    if CloneText ~= nil then
        if CloneText.Position == UDim2.new(0.1, 0, 0.65, 0) then
            CloneText.Position = CloneText.Position - UDim2.new(0, 0, 1, 0)
        else
            CloneText.Position = UDim2.new(0.1, 0, 0.65, 0)
        end 
    end
end

game.ReplicatedStorage.chatFunction.OnServerEvent(Chat)
