How to define player in DataStore 2 for rebirths?

I was trying to define a player in a leaderstats DataStore2 script for rebirths since if i use

if player:FindFirstChild("leaderstats") and player.leaderstats:FindFirstChild("Rebirths") player.leaderstats.Rebirths.Value = player.leaderstats.Rebirths.Value + 1

This wouldn't work since my DataStore2 script prevents updated values in the IntValue in the leaderstats folder of a player. I wanted to use RebirthStore:Increment(1, defaultValue) in a DataStore2 script. I've created this and it keeps saying Player is not a valid member of Players. Basically i need help in designing a way to define players in this script.

local Player = game:GetService("Players"):GetPlayers()
game.Players.Player:WaitForChild("PlayerGui").ScreenGui.Frame.TextButton.MouseButton1Down:Connect(function(player)
    local RebirthStore = DataStore2("Rebirths", player)
    local Player = game:GetService("Players"):GetPlayers()
    local ItemStore = DataStore2("Items", player)
    local RebirthStore = DataStore2("Rebirths", player)
    local CashStore = DataStore2("Cash", player)
    local TotalStore = DataStore2("Total", player)
        for p in ipairs(Player) do
            if Player.leaderstats.Cash.Value >= 14 then
               RebirthStore:Increment(1, defaultValue)
               CashStore:Set(0)
               ItemStore:Set(0)
               script.Parent.Parent.Visible = false
            elseif Player.leaderstats.Cash.Value <= 14 then
        script.Parent.Text = "Cant Afford!"
        script.Parent.TextColor3 = Color3.fromRGB(255, 0, 0)
        wait(1)
        script.Parent.Text = "Rebirth?"
        script.Parent.TextColor3 = Color3.fromRGB(85, 0, 127)


        end
        end
        end)
