How Do I Make it so the script only runs when the tool is equipped?

Currently whenever I press e it runs the script but I only want it to run when the tool is equipped

local tool = script.Parent
local uis = game:GetService("UserInputService")
local rs = game:GetService("ReplicatedStorage")
local Nogr = rs.nogr

tool.Equipped:Connect(function()
	uis.InputBegan:Connect(function(input)
		if input.KeyCode == Enum.KeyCode.E then
	     Nogr:FireServer()
		end
	end)	
end)

im not the answer-er (lol) but i'll try to explain the code

local tool ,equipped= script.Parent,false --equipped is used as a debounce here
local uis = game:GetService("UserInputService") --getting userinputservice to detect input
local rs = game:FindService("ReplicatedStorage") --self explanatory
local Nogr = rs:WaitForChild"nogr" --self explanatory

tool.Equipped:Connect(function()equipped=true;end) --the variable equipped becomes true if the tool is equipped
tool.Unequipped:Connect(function()equipped=false;end) --the variable equipped becomes false if the tool is unequipped 
uis.InputBegan:Connect(function(input)if not equipped then return end --code ends if equipped is false
        if input.KeyCode == Enum.KeyCode.E then --if the user pressed 'E'
         Nogr:FireServer() --fires the remote event 
        end
    end)
