when player touch part it change text in gui?

--[[
    This is a LocalScript. Insert it into StarterGui.
--]]

local gui = game.StarterGui["YourGuiName"]

local frame = gui["YourFrameName"]

local t = frame["YourTextName"]

game.ReplicatedStorage.TouchedFunction:FireServer()

game.ReplicatedStorage.TouchedFunction.OnClientEvent:Connect(function()
    t.Text = "hello lol" -- You can edit this however you like
end)

Server:

--[[
    This is a server script. You should insert it into ServerScriptService
--]]

game.ReplicatedStorage.TouchedFunction.OnServerEvent:Connect(function(plr)
    workspace["YourPartName"].Touched:Connect(function(hit)
        if hit.Parent then
            if hit.Parent:FindFirstChildOfClass("Humanoid") then
                local plr2 = game.Players:FindFirstChild(hit.Parent.Name)

                if plr2.Name == plr.Name then
                    game.ReplicatedStorage.TouchedFunction:FireClient(plr)
                end
            end
        end
    end)
end)

EDIT: I accidentally made an error on the Server, fixed it now!

EDIT2: Fixed the LocalScript. Replace YourGuiName, YourFrameName, and YourTextName with whatever the name of it is.

Good day!
