why isnt the gui opening when i touch the part?

I have tried almost everything i can to fix it but im not gettig no error message so i dont know what to do i was wondering if one of you can help me solve this issue here is the code:

local frame = game.StarterGui.ShopGui.AURA_SHOP_NAME
local frame2 = game.StarterGui.ShopGui.MAIN_FRAME
local part = game.Workspace["Aura shop"].Shop.ShopPart

part.Touched:Connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		frame.Visible = true
		frame2.Visible = true
	end
end)

part.TouchEnded:Connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		frame.Visible = false
		frame2.Visible = false
	end
end)

Assuming this is a Script, you have three issues.

1. Scripts execute on the server, so they don't have access to a player's UI elements, which are only visible on the client. (With some exceptions). So you'll need to convert this to a LocalScript or use a RemoteEvent to communicate between the server and client.
2. You are modifying the UI in the StarterGui, which are not the same elements that are visible to a player. Those elements are copied into the PlayerGui when their character spawns.
3. Many parts on your character model can fire the Touched and TouchEnded signals, so you need to do some simple accounting to only hide the UI once all of the parts stop touching.

To fix these issues, add a RemoteEvent to ReplicatedStorage, and try this :

-- find the remote event
local remoteEvent = game.ReplicatedStorage.RemoteEvent

-- keep a dictionary to count how many parts are touching the shop
local counts = {} -- [player name] : counter 

-- find the shop part
local part = game.Workspace["Aura shop"].Shop.ShopPart

part.Touched:Connect(function(hit)
     -- when a player touches the shop, add one to the counter
     local player = game.Players:GetPlayerFromCharacter(hit.Parent)
     if player then
         if not counts[player.Name] then
             counts[player.Name] = 0

             -- a player has just started touching the shop, show the screen
             remoteEvent:FireClient(player, true)
         end

         counts[player.Name] += 1
    end
end)


part.TouchEnded:Connect(function(hit)
    -- when the player stops touching, subtract one from the counter
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        counts[player.Name] -= 1

        if counts[player.Name] == 0 then
            -- all the parts have stopped touching the shop, hide it
            remoteEvent:FireClient(player, false)
            counts[player.Name] = nil
        end
    end
end)

Then put a LocalScript in the StarterGui, it will listen for when the server tells the client to show the shop.

-- find the UI elements
local shopGui = script.Parent.ShopGui
local frame = shopGui.AURA_SHOP_NAME
local frame2 = shopGui.MAIN_FRAME

-- find the remote event
local remoteEvent = game.ReplicatedStorage.RemoteEvent

-- listen for messages from the server
remoteEvent.OnClientEvent:Connect(function(isVisible)
    frame1.Visible = isVisible
    frame2.Visible = isVisible
end)
