How to subtract one from the total position of this?

while true do
    wait(1)
    local target = findNearestTorso(script.Parent.HumanoidRootPart.Position)
    if target ~= nil then
        script.Parent.Humanoid:MoveTo(target.Position, target)
        load3:Stop()
        load:Play()
         script.Parent.Humanoid.MoveToFinished:Wait()
        load:Stop()
        load2:Play()
        load2:Stop()
        load3:Play()
    end

end

Basically, when the robot comes to you it just pushes you so the move to never finishes, there for the animations doesn't play, I tried subtracting the values using - vector3(1,1,1) but it usually gave me a table error.
