[UNSOLVED] Help with a Huge Script (2)?

So instead of editing my last thread, I just decided to put it into a new Question because I changed it so much. It still doesn't work, but it's a lot cleaner, and in two scripts now. So, if you didn't see the last thread, I'm trying to script an RPG game. I want it so that when a player connects, a function assigns a bunch of BoolValues and NumberValues to represent Experience, Levels, HP, etc. Whenever I test it, it gives me in the output "Gold is not a valid member of Player", "Gems is not a valid member of Player" etc, for each of the Values, and I'm not sure what I did wrong. Here's the code:

--THIS IS IN A REGULAR SCRIPT, NOT LOCALSCRIPT
--Player value Variables
Gold = Instance.new("NumberValue")
Gems = Instance.new("NumberValue")
PlayerLevel = Instance.new("NumberValue")
Exp = Instance.new("NumberValue")
HP = Instance.new("NumberValue")
Quest1 = Instance.new("BoolValue")
Quest2 = Instance.new("BoolValue")
Quest3 = Instance.new("BoolValue")
Quest4 = Instance.new("BoolValue")
Quest5 = Instance.new("BoolValue")
Player = game.Players.LocalPlayer
Gold = 10
Gems = 0
PlayerLevel = 1

--Gui frame variables
ScreenGui = game.StarterGui.ScreenGui
ShopBG = ScreenGui.ShopBG
QuestsBG = ScreenGui.QuestsBG
StatsBG = ScreenGui.StatsBG
OptionsBG = ScreenGui.OptionsBG

--Start of functions
wait(3)


a = game.Players.LocalPlayer:GetChildren()

function assignValues() --assigns LocalPlayer all necessary values
repeat wait() until Player --waits until Player is loaded before assigning values
for i,v in pairs(a) do
    if v:IsA("BoolValue" or "NumberValue") then --makes sure that the Player doesn't have values assigned already
        Player.MaxHealth = Player.HP.Value
    else --if they don't have values, then it assigns them values

    Gold.Parent = Player
    Gold.Name = "Gold"
    Gold.Value = 10
    Gems.Parent = Player
    Gems.Name = "Gems"
    Gems.Value = 0
    PlayerLevel.Parent = Player
    PlayerLevel.Name = "PlayerLevel"
    PlayerLevel.Value = 1
    Exp.Parent = Player
    Exp.Name = "Exp"
    HP.Parent = Player
    HP.Name = "HP"
    Quest1.Parent = Player
    Quest1.Name = "Quest1"
    Quest1.Value = false
    Quest2.Parent = Player
    Quest2.Name = "Quest2"
    Quest2.Value = false
    Quest3.Parent = Player
    Quest3.Name = "Quest3"
    Quest3.Value = false
    Quest4.Parent = Player
    Quest4.Name = "Quest4"
    Quest4.Value = false
    Quest5.Parent = Player
    Quest5.Name = "Quest5"
    Quest5.Value = false

end     
end
end


game.Players.PlayerAdded:connect(assignValues)

There is another script that assigns XP and Levels up the Player. I'm not sure if you need to see that too, but I'll include the code:

--THIS IS IN A LOCALSCRIPT
--Player value Variables
Gold = Instance.new("NumberValue")
Gems = Instance.new("NumberValue")
PlayerLevel = Instance.new("NumberValue")
Exp = Instance.new("NumberValue")
HP = Instance.new("NumberValue")
Quest1 = Instance.new("BoolValue")
Quest2 = Instance.new("BoolValue")
Quest3 = Instance.new("BoolValue")
Quest4 = Instance.new("BoolValue")
Quest5 = Instance.new("BoolValue")
Player = game.Players.LocalPlayer
Gold = 10
Gems = 0
PlayerLevel = 1

--Gui frame variables
ScreenGui = game.StarterGui.ScreenGui
ShopBG = ScreenGui.ShopBG
QuestsBG = ScreenGui.QuestsBG
StatsBG = ScreenGui.StatsBG
OptionsBG = ScreenGui.OptionsBG

--Start of functions
wait(3)


while true do
local xps = {0, 100, 300, 600, 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6500, 8000, 9500, 11000, 12500, 14000, 15500, 18000, 21000, 25000, 30000, 35000, 40000, 45000, 50000, 57500, 65000, 72500, 82500, 100000};
local xp = Player.Exp.Value;
local level = 1;
while xps[level] and xps[level] <= xp do
    level = level + 1;
end

Player.HP.Value = 200 + 100 * Player.PlayerLevel.Value;

end
