My rebirth script is broken and doesn't allow me to rebirth more than once?

This script isn't allowing me to rebirth more than once. Can anyone help with how to let me rebirth multiple times?

I have a rebirth script in a ScreenGui in StarterGUI, and a ServerScriptService script for RemoteFunctions and RemoteEvents.

The first code block is the GUI script, and the second being for RemoteFunctions and RemoteEvents.

local replicatedStorage = game:GetService("ReplicatedStorage")
local starterRebirthAmount = 5000

local player = game.Players.LocalPlayer
local mainFrame = script.Parent:WaitForChild("MainFrame")
local rebirthMenu = mainFrame:WaitForChild("RebirthMenu")
local mainButton = script.Parent:WaitForChild("MainButton")
local rebirthButton = rebirthMenu:WaitForChild("RebirthButton")
local strengthToRebirth = rebirthMenu:WaitForChild("StrengthToRebirth")
local rebirths = player:WaitForChild("leaderstats").Rebirths


strengthToRebirth.Text = "To rebirth, you will need "..math.floor((starterRebirthAmount + (rebirths.Value) * math.sqrt(1000000))).." strength to rebirth"

mainButton.MouseButton1Click:Connect(function()
	mainFrame.Visible = not mainFrame.Visible
end)

rebirthButton.MouseButton1Click:Connect(function()
	local result = replicatedStorage.Remotes.Rebirth:InvokeServer()
	
	if result == true then
		rebirthButton.Text = "Successfully Rebirthed!"
		wait(1)
		rebirthButton.Text = "CLICK HERE TO REBIRTH"
		
	elseif result == "NotEnoughStrength" then
		rebirthButton.Text = "Oh no! You don't have enough strength to rebirth. Keep Lifting!"
		wait(1)
		rebirthButton.Text = "CLICK HERE TO REBIRTH"
	end
end)

rebirths:GetPropertyChangedSignal("Value"):Connect(function()
	math.floor((starterRebirthAmount * (rebirths.Value) * math.sqrt(1000000)))
end)

replicatedStorage.Remotes.Rebirth.OnServerInvoke = function(player)
	
	if not remoteData:FindFirstChild(player.name) then return "NoFolder" end
	
	local rebirths = player.leaderstats.Rebirths
	
	if player.leaderstats.Strength.Value >= (math.floor((starterRebirthAmount * (rebirths.Value) * math.sqrt(1000000)))) then
		
		rebirths.Value = rebirths.Value + 1
		
		player.leaderstats.Strength.Value = 0
		
		player:LoadCharacter()
		
		return true
	else return "NotEnoughRebirth"
		
	end
end
