Why cant my Shop script locate the Value of the Price?

my player is defind here since i couldnt figure out how to find local player in a normal script

game.Players.PlayerAdded:Connect(function(player)

	local price = player.PlayerGui:WaitForChild("Gui").Main.Info.Price
	local leaderstats = player:FindFirstChild("leaderstats")
	local Cash = leaderstats:FindFirstChild("Cash")

	if Cash.Value >= price.Value then
	Cash.Value = Cash.Value - price.Value

The "price" is a intValue. When I did

local price = 100

it worked. But when i changed it back to

local price = player.PlayerGui:WaitForChild("Gui").Main.Info.Price

it didnt work. This is all in a normal script in workspace. Can someone explain why my script cant find the value of the "price" The "price" is located in the Gui
