attempt to index nil with 'LeftLowerLeg'? What does this mean?

Asked by

I'm making ice skates for my game and I'm trying to get them on the player but this pops up, "attempt to index nil with 'leftlowerleg'. I don't get it. Here is the part of my script that has it.

1local Y = Instance.new("Weld")
2Y.Part0 = player.Character.LeftLowerLeg
3Y.Part1 = g.Middle
4Y.C0 = CFrame.new(0, 0, 0)
5Y.Parent = Y.Part0

here is the whole script

01local Skate = workspace.IceSkates
02game.Players.PlayerAdded:connect(function(player)
03    local g = Skate.Leg1:clone()
04        g.Parent = player.Character
05        local C = g:GetChildren()
06        for i=1, #C do
07            if C[i].className == "Part" then
08                local W = Instance.new("Weld")
09                W.Part0 = g.Middle
10                W.Part1 = C[i]
11                local CJ = CFrame.new(g.Middle.Position)
12                local C0 = g.Middle.CFrame:inverse()*CJ
13                local C1 = C[i].CFrame:inverse()*CJ
14                W.C0 = C0
15                W.C1 = C1
16                W.Parent = g.Middle
17            end
18                local Y = Instance.new("Weld")
19                Y.Part0 = player.Character.LeftLowerLeg
20                Y.Part1 = g.Middle
21                Y.C0 = CFrame.new(0, 0, 0)
22                Y.Parent = Y.Part0
23        end
24 
25        local h = g:GetChildren()
26        for i = 1, # h do
27            h[i].Anchored = false
28            h[i].CanCollide = false
