How do I make a button only fire when you have a certain amount of value?

I am currently working on a game called "Pet Rock Sim" and I am looking into making a shop to buy your pets.The way you buy a pet is simply click on a dedicated button for it, but I don't know how to make that button only fire when you have a certain amount of cash.

Add the RemoteEvent to the ReplicateStorage.

-- Script

--// Variables
local RemoteEvent = game.ReplicatedStorage:WaitForChild("RemoteEvent")

--// Remote Event
RemoteEvent.OnServerEvent:Connect(function(plr, Price)
	if plr and Price then
		local Points = plr:FindFirstChild("leaderstats"):FindFirstChild("Points").Value
		if Points then
			if Points >= Price then
				plr:FindFirstChild("leaderstats"):FindFirstChild("Points").Value = plr:FindFirstChild("leaderstats"):FindFirstChild("Points").Value - Price
				print(Points)
				print(Price)
				RemoteEvent:FireClient(plr)
			end
		end
	end
end)

-- Local Script

--// Variables
local RemoteEvent = game.ReplicatedStorage:WaitForChild("RemoteEvent")
local Button = script.Parent:WaitForChild("TextButton")

--// Settings
local Price = 100
local plr = game.Players.LocalPlayer

--// Button Event
Button.MouseButton1Click:Connect(function()
	RemoteEvent:FireServer(Price)
end)

--// RemoteEvent
RemoteEvent.OnClientEvent:Connect(function(plr)
	print("Successfully")
end)
