Why does my image not show when the mouse is over the text button?

first off here's my code

local player = game.Players.LocalPlayer
local cash = player:WaitForChild('leaderstats').Cash
local price = 1500 
local tip = script.Parent.Parent.GunPrice
local picture = script.Parent.Parent.ItemPic

script.Parent.MouseButton1Click:connect(function()
	if cash.Value >= price and not player.Backpack:FindFirstChild('MP40') and not player.Character:FindFirstChild('MP40')then
		game.ReplicatedStorage.MP40:Clone().Parent = player.StarterGear 
		game.ReplicatedStorage.MP40:Clone().Parent = player.Character
		cash.Value = cash.Value - price	
		else if player.StarterGear:FindFirstChild('MP40')then
			tip.Text = 'Already Owned'
			wait(2)
			tip.Text = 'Price: $1500'
		else	
			tip.Text = 'Not Enough Cash'
			wait(2)
			tip.Text = 'Price: $1500'
	
		end	
	end	
end)

script.Parent.MouseEnter:connect(function()
tip.Visible = true	
tip.Text = "Price: $1500"
picture.Image = script.ImageValue.Value
end)

script.Parent.MouseLeave:connect(function()
tip.Text = "Price:"
picture.Image = script.ImageValue.Value
end)

this is a shop gui button script i made and everything works but the picture coming up in the mouse enter function it shows up blank and there are no errors in the output window

i have the asset id in a string value inside the script

You set the image to the same thing on MouseEnter and MouseLeave, so it will never change.
