Can someone fix my Anti-Gravity Script? I need it fixed ASAP!! [closed]

I need some to fix this script:

workspace = game.Workspace:getChildren()

antigrav = 0 --edit this for force of antigravity
gravforce = 195.5729088953 * antigrav


function check(object)
    for i = 1, #object do
    wait()
    add(object[i])
    end
end

function add(object)
    if object.className == ("Model") or object.className == ("Tool") or object.className == ("Accoutrement") then
    check(object:getChildren())
    end
    if object.className == ("Part") or object.className == ("Truss") then
        if object.Anchored == false then
        local bforce = Instance.new("BodyForce")
        bforce.force = Vector3.new(0, ((object:getMass())*gravforce), 0)
        bforce.Parent = object
        end
    end
end
check(workspace)

game.Workspace.ChildAdded:connect(function(object) add(object) end)
