I'm making a button that gives the player jumpboost but it dosen't work?

Info/setup of button: https://i.postimg.cc/WbFd0zxg/Info.png It's also not displaying if you don't have enough money or if it was purchased etc. It does give you the jumpboost even if you don't have "Coins" for it for some reason?

the code for the button:

 player = game.Players.LocalPlayer
 
 script.Parent.MouseButton1Click:Connect(function()
 
 if player.Character.Humanoid.JumpPower == 65 then
 
 script.Parent.Text "Already Bougth!"
 
 if player:FindFirstChild("leaderstats") then
 
 if player.leaderstats.Coins.Value == 10 then
 
 player.leaderstats.Coins.Value = player.leaderstats.Coins.Value -10
 
 script.Parent.Text = "Purchased"
 
 player.Character.Humanoid.JumpPower = 65
 
 elseif player.leaderstats.Coins.Value >= 10 then
 
 script.Parent.Text = "Not enough money!"

 end
 
 end
 
 end
 
 end)

my leaderstats (extra info):

game.Players.PlayerAdded:connect(function(plr)

local stats = Instance.new("BoolValue",plr)

stats.Name = "leaderstats"

local Coins = Instance.new("IntValue",stats)

Coins.Name = "Coins"

Coins.Value = 0

end)
