How do I make a Part w/ a ClickDetector give me a tool?

I want to make a Part that when I click on it, gives me a Sword. I'm using a normal script.

I receive this error when I play my game in Studio:

• Workspace.Part.ClickDetector.Script:9: attempt to index local 'player' (a nil value)

clickDetector = script.Parent
giver = clickDetector.Parent
sword = game.ServerStorage.ClassicSword:Clone()



function giveSwordToPlayer()
	local player = game.Players.LocalPlayer
	local playerBackpack = player.Backpack
    sword.Parent = playerBackpack
end



clickDetector.MouseClick:Connect(giveSwordToPlayer())

Also if anyone has any valuable sources to expand my knowledge on Rbx.lua other than the new Robloxdev wiki, please let me know.

Thank you
