Inventory and Mining

I have a inventory that is activated by click a Gui but i want it to be activated by click e the inventorys name in starterGui is Inventory i also want a brick that when you touch it it with a tool it goes into your inventory and disapears

Plz have instructions and be clear of what you say

To press E for inventory : IN A LOCALSCRIPT

mouse = game.Players.LocalPlayer:GetMouse() --gets the players mouse
open = false --check if inventory is open or closed 
mouse.KeyDown:connect(function(key) -- fires when player presses key
if key == "e" then
if open == false then
open = true
game.Players.LocalPlayer.PlayerGui.StarterGui.Inventory.Visible = true
-- BE SURE TO CHANGE STARTERGUI TO YOUR GUI
else
open = false
game.Players.LocalPlayer.PlayerGui.StarterGui.Inventory.Visible = false
-- BE SURE TO CHANGE STARTERGUI TO YOUR GUI
end
end
end)

To give tool : PUT IN NORMAL SCRIPT IN PART TO TOUCH

script.Parent.Touched:connect(function(part)--fires on touch
local player = game.Players:GetPlayerFromCharacter(part.Parent)--get player
	if player then --check if player
		tool = game.ReplicatedStorage.Tool:Clone()--clone tool
		tool.Parent = player.Backpack--put in players backpack
	end
end)

Should work, Good luck.
