Problem with a Popup GUI with a NPC? #NPCPopUp

I've been trying to create a NPC Chat System. My idea is that i want a npc inside a block. And, when you touch the block a Frame pops up with text. How would i do that i've tried this

local Part = script.Parent
local Frame = game.StarterGui.IntelC1

    Part.Touched:connect(function(HIT)
        local H = HIT.Parent:FindFirstChild("Humanoid")
        if H then
            local Player = game.Players:GetPlayerFromCharacter(HIT.Parent)
           Frame.Parent = game.Player.PlayerGui 
           Player.PlayerGui.IntelC1.CHFrame.Visible = true
    end end)

But, i got this error "18:30:45.343 - Player is not a valid member of DataModel" Could anyone help? :) Thanks in advance. Got a new error.
