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
