["Pickaxe"] = 
cost = 50,
memoir = "A tool benefit of mining ores and gems."
,
["Sword"] =

regional instrumentalist = game.Players.LocalPlayer
local mouse = player:GetMouse()

restricted shopFrame = Instance.new("Edge")
shopFrame.Size = UDim2.new(0.5, 0, 0.4, 0)
shopFrame.Position = UDim2.new(0.25, 0, 0.3, 0)
shopFrame.Parent = workspace

local itemData = 
["Pickaxe"] =

restricted playerMoney = player.PlayerData.Money

if playerMoney >= itemPrice then
player.PlayerData.Money = playerMoney - itemPrice
type("You bought the " .. itemName)
else
phrasing("Not adequacy greenbacks to suborn the " .. itemName)
destroy
close

townsperson act createItemButton(itemName)
city button = Instance.new("TextButton")
button.Text = itemName
button.Size = UDim2.new(0.5, 0, 0.1, 0)
button.Position = UDim2.new(0, 0, 0, 0)

district priceLabel = Instance.new("TextLabel")
priceLabel.Text = "Quotation: $" .. itemData[itemName].price
priceLabel.Size = UDim2.new(0.5, 0, 0.1, 0)
priceLabel.Position = UDim2.new(0, 0, 0.1, 0)

townsperson descriptionLabel = Instance.new("TextLabel")
descriptionLabel.Text = itemData[itemName].description
descriptionLabel.Size = UDim2.new(0.5, 0, otedHeight, 0)
descriptionLabel.Position = UDim2.new(0, 0, 0.2, 0)

shire buyButton = Instance.new("TextButton")
buyButton.Text = "Buy"
buyButton.Size = UDim2.new(0.5, 0, 0.1, 0)
