I know why this script doesn't work, but can someone tell me how to click when a tool is equipped?

script.Parent.MouseClick:Connect(function(clicked)
	print(clicked)
	if clicked.Backpack["Basic Capsule"].Activated() then
		print("yay")
	end
end)

This script has an obvious error, but I'm trying to make it so when a tool is equipped, you can click.

nvm i fixed it myself i just turned the if clicked into a function
