can someone help me adjust price of buying upgrades please? (cash and Ko's)?

What I am wanting to do is use cash and ko's to buy weapons and upgrades.

I have it now were all you need is cash

ok the last script didn't work out very well this is the script that I am using I am not sure if I need to save them some were like I did the cash or what.

PurchaseHandler:

objects = {}
teamcolor = BrickColor.new(script.Parent.Name)
config = script.Parent.Parent.Parent.Configuration
wait(1)

script.Parent.Essentials.Spawn.TeamColor = teamcolor
script.Parent.Essentials.Spawn.BrickColor = teamcolor

script.Parent.Essentials.Collector.Touched:connect(function(hit)
	if hit:FindFirstChild("Cash") then
		script.Parent.Cash.Value = script.Parent.Cash.Value + hit.Cash.Value
		Instance.new("Sparkles",hit).Color=Color3.new(math.random(1,255)/255,math.random(1,255)/255,math.random(1,255)/255)
		game.Debris:AddItem(hit,0.1)
	end
end)


script.Parent.Essentials.Giver.Touched:connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if player ~= nil then
		if script.Parent.Owner.Value == player then
			if hit.Parent:FindFirstChild("Humanoid") then
				if hit.Parent.Humanoid.Health > 0 then
					local cashmoney = game.ServerStorage.MoneyStorage:FindFirstChild(player.Name)
					if cashmoney ~= nil then 
						cashmoney.Value = cashmoney.Value + script.Parent.Cash.Value
						script.Parent.Cash.Value = 0
					end
				end
			end
		end
	end
end)

script.Parent:WaitForChild("Buttons")
for i,v in pairs(script.Parent.Buttons:GetChildren()) do
	if v:FindFirstChild("Head") then
		
		local object = script.Parent.Purchases:FindFirstChild(v.Object.Value)
		if object ~= nil then
			objects[object.Name] = object:Clone()
			object:Destroy()
		else
			print("Button: "..v.Name.." is missing its object and has been removed.")
			v.Head.CanCollide = false
			v.Head.Transparency = 1
		end
								
		if v:FindFirstChild("Dependency") then
			v.Head.CanCollide = false
			v.Head.Transparency = 1
			coroutine.resume(coroutine.create(function()
				if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then
					if config.ButtonFadeInDependency.Value == true then
						for i=1,20 do
							wait(config.ButtonFadeInTime.Value/20)
							v.Head.Transparency = v.Head.Transparency - 0.05
						end
					end
					v.Head.CanCollide = true
					v.Head.Transparency = 0
				end
			end))
		end
		
		v.Head.Touched:connect(function(hit)
			local player = game.Players:GetPlayerFromCharacter(hit.Parent)
			if v.Head.CanCollide == true then
				if player ~= nil then
					if script.Parent.Owner.Value == player then
						if hit.Parent:FindFirstChild("Humanoid") then
							if hit.Parent.Humanoid.Health > 0 then
								local cashmoney = game.ServerStorage.MoneyStorage:FindFirstChild(player.Name)
								if cashmoney ~= nil then
									if cashmoney.Value >= v.Price.Value then
										cashmoney.Value = cashmoney.Value - v.Price.Value
										objects[v.Object.Value].Parent = script.Parent.PurchasedObjects
										if config.ButtonExplodeOnBuy.Value == true then
											
																					
											local explosion = Instance.new("Explosion",workspace)
											explosion.Position = v.Head.Position
											explosion.DestroyJointRadiusPercent = 0
											explosion.BlastPressure = 0
										end
										if config.ButtonFadeOutOnBuy.Value == true then
											v.Head.CanCollide = false
											coroutine.resume(coroutine.create(function()
												for i=1,20 do
													wait(config.ButtonFadeOutTime.Value/20)
													v.Head.Transparency = v.Head.Transparency + 0.05
												end
											end))
										else
											v.Head.CanCollide = false
											v.Head.Transparency = 1
										end
									end
								end
							end
						end
					end
				end
			end
		end)
		
	end
end

Here is my leaderboard script:

	local stats = player:findFirstChild("leaderstats")
	if stats ~= nil then
		local deaths = stats:findFirstChild("Wipeouts")
		deaths.Value = deaths.Value + 1
		
		-- do short dance to try and find the killer

		local killer = getKillerOfHumanoidIfStillInGame(humanoid)

		handleKillCount(humanoid, player)
	end
end

function onPlayerRespawn(property, player)
	-- need to connect to new humanoid
	
	if property == "Character" and player.Character ~= nil then
		local humanoid = player.Character.Humanoid
			local p = player
			local h = humanoid
			humanoid.Died:connect(function() onHumanoidDied(h, p) end )
	end
end

function getKillerOfHumanoidIfStillInGame(humanoid)
	-- returns the player object that killed this humanoid
	-- returns nil if the killer is no longer in the game

	-- check for kill tag on humanoid - may be more than one - todo: deal with this
	local tag = humanoid:findFirstChild("creator")

	-- find player with name on tag
	if tag ~= nil then
		
		local killer = tag.Value
		if killer.Parent ~= nil then -- killer still in game
			return killer
		end
	end

	return nil
end

function handleKillCount(humanoid, player)
	local killer = getKillerOfHumanoidIfStillInGame(humanoid)
	if killer ~= nil then
		local stats = killer:findFirstChild("leaderstats")
		if stats ~= nil then
			local kills = stats:findFirstChild("KOs")
			if killer ~= player then
				kills.Value = kills.Value + 1
				
			else
				kills.Value = kills.Value - 1
				
			end
		end
	end
end
