[UNSOLVED] Help with two questions?

Okay, I have two questions. Here is the first. So, this one is pretty simple, how would I loop this function forever?

function LevelUp()
	if Player.Exp.Value >= 100 then
		Player.PlayerLevel.Value = 2
	elseif Player.Exp.Value >= 300 then
		Player.PlayerLeve.Valuel = 3
	elseif Player.Exp.Value >= 600 then
		Player.PlayerLeve.Valuel = 4
	elseif Player.Exp.Value >= 1000 then
		Player.PlayerLevel.Value = 5
	elseif Player.Exp.Value >= 1500 then
		Player.PlayerLevel.Value = 6
	elseif Player.Exp.Value >= 2000 then
		Player.PlayerLevel.Value = 7
	elseif Player.Exp.Value >= 2500 then
		Player.PlayerLevel.Value = 8
	elseif Player.Exp.Value >= 3000 then
		Player.PlayerLevel.Value = 9
	elseif Player.Exp.Value >= 4000 then
		Player.PlayerLevel.Value = 10
	elseif Player.Exp.Value >= 5000 then
		Player.PlayerLevel.Value = 11
	elseif Player.Exp.Value >= 6500 then
		Player.PlayerLevel.Value = 12
	elseif Player.Exp.Value >= 8000 then
		Player.PlayerLevel.Value = 13
	elseif Player.Exp.Value >= 9500 then
		Player.PlayerLevel.Value = 14
	elseif Player.Exp.Value >= 11000 then
		Player.PlayerLevel.Value = 15
	elseif Player.Exp.Value >= 12500 then
		Player.PlayerLevel.Value = 16
	elseif Player.Exp.Value >= 14000 then
		Player.PlayerLevel.Value = 17
	elseif Player.Exp.Value >= 15500 then
		Player.PlayerLevel.Value = 18
	elseif Player.Exp.Value >= 18000 then
		Player.PlayerLevel.Value = 19
	elseif Player.Exp.Value >= 21000 then
		Player.PlayerLevel.Value = 20
	elseif Player.Exp.Value >= 25000 then
		Player.PlayerLevel.Value = 21
	elseif Player.Exp.Value >= 30000 then
		Player.PlayerLevel.Value = 22
	elseif Player.Exp.Value >= 35000 then
		Player.PlayerLevel.Value = 23
	elseif Player.Exp.Value >= 40000 then
		Player.PlayerLevel.Value = 24
	elseif Player.Exp.Value >= 45000 then
		Player.PlayerLevel.Value = 25
	elseif Player.Exp.Value >= 50000 then
		Player.PlayerLevel.Value = 26
	elseif Player.Exp.Value >= 57500 then
		Player.PlayerLevel.Value = 27
	elseif Player.Exp.Value >= 65000 then
		Player.PlayerLevel.Value = 28
	elseif Player.Exp.Value >= 72500 then
		Player.PlayerLevel.Value = 29
	elseif Player.Exp.Value >= 82500 then
		Player.PlayerLevel.Value = 30
	elseif Player.Exp.Value >= 100000 then
		Player.PlayerLevel.Value = 31
	else
	print("An error has occured with the LevelUp Function.")
	end
end

Basically, I want it to constantly check the Player's Exp to see if it is enough to level up.

===========================

And my second question relates to the above script, but in a different way. How would I award Exp to a player based on damage done to NPCs or Players? I want about 10 Exp awarded per 100 Damage done, but I have no idea how to do that. (The damage will be dealt with swords and bows/crossbows.) Also, 10-25 Gold should be random assigned (Player.Gold.Value), and a rare chance to get 1 or 2 gems (Player.Gems.Value) should be awarded per 300 damage or so. (The weakest NPC will have 300 damage, so you don't have to worry about stacking between NPC damage.)

Thanks!

I think you don't have to loop it , but if you will use the "While true do" Or the "Repeat" method!

-- for this script lets imagine the script is in the handle of the tool (SWORD)

script.Parent.Touched:Connect(function(touched)
if hit.Parent.Humanoid ~= nil then
npc = hit.Parent
npcHealth == hit.Parent.Humanoid.Health

wait() until npcHealth  = npcHealth -100
for _,v in pairs(npcHealth )  do
if npcHealth == 200 then

Player.Exp.Value = Player.Exp.Value + 10 

else return
				end
										-- I HOPE THIS WORKS! :)
		end
end)

I'm not sure if it works! Good luck if it does!
