why wont FindFirstChildWhichIsA work on a i,v loop?

for i,v in pairs(game.Workspace:GetChildren()) do
	if v:FindFirstChildWhichIsA('Tool') then
		print('LOL')
	end

end

its supposed to print 6 LOL cause theres 6 tools but its not doing anything

I also need help doing

Looking for values inside the tools of workspace

the Value is a IntValue but this also dosent seem to work

for i,v in pairs(game.Workspace:GetChildren()) do
	Find =  v:FindFirstChildWhichIsA('Tool')
	if Find then
		Val = Find:FindFirstChild('Value')
		if Val then
			print(Val.Value)
		end
	end 
	

end
