A nil value problem?

This script, with the error, starts at line 23 with 'local g'. It should do the exact same thing as local h on line 4. But, it breaks and line 82 saying that 'g is a nil value' I do not understand why it is breaking...

found1 = script.Parent.Parent.PurchasedObjects:FindFirstChild("Dropper1")
builder1 = script.Parent.Parent.PurchasedObjects:FindFirstChild("Hut1")
builder2 = script.Parent.Parent.PurchasedObjects:FindFirstChild("Hut2")
local h
for _, v in pairs (builder1:GetChildren()) do
    local names = {
    ["Peter"] = true,
    ["Carson"] = true,
	["Hunter"] = true,
    ["Alex"] = true,
	["Joe"] = true,
    ["Bob"] = true,
	["Tyler"] = true,
    ["Colt"] = true,
    ["Reed"] = true,
    }
    if names[v.Name] ~= nil then
        h = v
        break
    end
end

local g
if script.Parent:FindFirstChild("builder2") then
for _, v in pairs (builder2:GetChildren()) do
    local names = {
	["Kristopher"] = true,
	["Dani"] = true,
	["Ember"] = true,
	["Akira"] = true,
	["Cat"] = true,
	["Kelsey"] = true,
	["Sibon"] = true
    }
    if names[v.Name] ~= nil then
        g = v
        break
    end
end
end

model1 = found1.disap:GetChildren()

  if found1 then
	if builder1.Available.Value == true then
		builder1.Available.Value = false

g can be nil

You write

if names[v.Name] ~= nil then
        g = v
        break
    end

But provide no escape condition for if g is then nil.
