[SOLVED] Sleeping at inn takes more cents each time you sleep?

local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local playerGui = player:WaitForChild("PlayerGui")
local humanoid = char:WaitForChild("Humanoid")

local dialog = game.ReplicatedStorage.Dialog
local interact = game.ReplicatedStorage.Interact

local price = 5

if player.Data.Coins.Value >= price then
    player.Data.Coins.Value = player.Data.Coins.Value - price -- This is the line that removes 5 coins each time.

    blackscreen.Parent = playerGui
    dialog.Continue.Visible = false
    dialog.Cancel.Visible = false
    dialog.NameBox.TextLabel.Text = ""
    dialog.Text.TextLabel.Text = ""
    dialog.Parent = game.ReplicatedStorage
    interact.Parent = game.ReplicatedStorage

    for i = 0, 1.02, 0.02 do
        blackscreen.Background.Size = UDim2.new(i, 0, i, 0)
        game:GetService("RunService").Heartbeat:Wait()
    end

    wait(2)

    for i = 1.02, -0.02, -0.02 do
        blackscreen.Background.Size = UDim2.new(i, 0, i, 0)
        game:GetService("RunService").Heartbeat:Wait()
    end

    player.Data.HP.Value = humanoid.MaxHealth
    humanoid.WalkSpeed = 25
    interact.TextLabel.Visible = true
end

What I'm trying to do is, whenever you sleep at an inn, it will take 5 coins and then you will have full HP. The problem is if you do it repeatedly, the price rises by 5 and I don't know why.
