Rebirth is not a valid member of Folder?

I dont know exactly what I did wrong, but every time I try to click rebirth on the GUI it shows up with an error called Rebirth is not a valid member of Folder.

  local replicatedStorage = game:GetService("ReplicatedStorage")

local remoteData = game:GetService("ServerStorage"):WaitForChild("RemoteData")

local starterRebirthAmount = 5000







local cooldown = 1



replicatedStorage.Remotes.Lift.OnServerEvent:Connect(function(player)

if not remoteData:FindFirstChild(player.Name) then return "NoFolder" end

local debounce = remoteData[player.Name].Debounce

if not debounce.Value then

debounce.Value = true

player.leaderstats.Strength.Value = player.leaderstats.Strength.Value + 25 * (player.leaderstats.Rebirths.Value + 1)

wait(cooldown)

debounce.Value = false

else

end

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(5000000)))) then

rebirths.Value = rebirths.Value + 1

player.leaderstats.Strength.Value = 0

player.LoadCharacter()

return true

else return "NotEnoughStrength"

end

end
