How do you fix a function that is being run from the last run?

I have a problem, basically I am making a rolling concept but when I use 'Skip' Button, the normal run which is 15 seconds will get collided in to next run, only starts happening when used skip function.

local Rarity = require(game.ReplicatedStorage.GameModules.Rarity)
local SkipButton = script.Parent.RollFrame.SkipButton
local _RandomSeed = nil
local _ItemSize = nil
local _Amount = 1
local _Timing = 15
local _Type = nil
local Chosen = nil
local ChosenFrame = nil
local Access = true
local Available = true

script.Event.Event:connect(function(Type,Amount,Timing)
		local Ready = false
		local Count = (script.Parent.RollFrame.ItemsFrame.Items.AbsoluteSize.X/script.Parent.RollFrame.ItemsFrame.Items.AbsoluteSize.Y)+4
		local Items = {}
		script.Parent.RollFrame.ItemsFrame.Items:ClearAllChildren()
		_Timing = Timing
		_Amount = Amount
		_Type = Type
		script.Parent.RollFrame.Visible = true
		script.Parent.RewardFrame.Visible = false
		script.Parent.RollFrame.SkipButton.Visible = true
		script.Parent.RollFrame.Amount.Text = "x"..Amount
		script.Parent.RollFrame.ItemsFrame.Items.Position = UDim2.new(0,0,0,0)
		print(Count)
		local Tick = tick()
		math.randomseed(Tick)
		if string.lower(Type) == "common" then
			Items = Rarity.GetRarity(80,20)
			Ready = true
		elseif string.lower(Type) == "uncommon" then 
			Items = Rarity.GetRarity(20,80)
			Ready = true
		end
		
		if Ready == true then
			for i = 0, Count do
				local Item = Items[math.random(#Items)]
				local Frame = script.Template:Clone()
				Frame.Background.Number.Text = i
				Frame.Parent = script.Parent.RollFrame.ItemsFrame.Items
				Frame.Name = tostring(Item)
				Frame.Image.Color.ImageColor3 = Rarity.GetRarityColor(game.ReplicatedStorage.Items[Item].Price.Value)
				Frame.Image.Image = "http://www.roblox.com/Game/Tools/ThumbnailAsset.ashx?fmt=png&wd=110&ht=110&aid="..Item
				Frame.Size = UDim2.new(0,Frame.AbsoluteSize.Y,1,0)
				Frame.Position = UDim2.new(0,Frame.AbsoluteSize.Y*i,0,0)
				if i == 109 then
					_Amount = _Amount - 1
					Chosen = Item
					ChosenFrame = Frame
				end
			end
		end
		
		local RandomSeed = math.random()*script.Parent.RollFrame.ItemsFrame.Items.AbsoluteSize.Y/2
		_RandomSeed = RandomSeed
		_ItemSize = -script.Parent.RollFrame.ItemsFrame.Items.AbsoluteSize.X
		Actions(Timing)
	end)

function Actions(Timing)
	script.Parent.RollFrame.ItemsFrame.Items:TweenPosition(UDim2.new(0, _ItemSize + 1000 + _RandomSeed, 0, 0), "Out", "Quart", Timing,true)
	if Access == true then
		wait(Timing/2)
		script.Parent.RollFrame.SkipButton.Visible = false
		if Available == true then
			wait(Timing/2)
			ChosenFrame.Background.ImageColor3 = Color3.fromRGB(255, 255, 255)
			wait(1)
			AwardRun(game.ReplicatedStorage.Items[Chosen].Name)
			print("Normal")
		end
	else
		script.Parent.RollFrame.SkipButton.Visible = false
		script.Parent.RollFrame.ItemsFrame.Items:TweenPosition(UDim2.new(0, _ItemSize + 1005 + _RandomSeed, 0, 0), "Out", "Quart", 0.5,true)
		wait(0.8)
		ChosenFrame.Background.ImageColor3 = Color3.fromRGB(255, 255, 255)
		wait(1)
		AwardRun(game.ReplicatedStorage.Items[Chosen].Name)
		print("Skip")
	end
end

function AwardRun(Item)
	local ItemColor = Rarity.GetRarityColor(game.ReplicatedStorage.Items[Item].Price.Value)
	local RollFrame = script.Parent.RollFrame
	local RewardFrame = script.Parent.RewardFrame
	RollFrame.Visible = false
	RewardFrame.Visible = true
	RewardFrame.Image.Image = "http://www.roblox.com/Game/Tools/ThumbnailAsset.ashx?fmt=png&wd=110&ht=110&aid="..Item
	RewardFrame.Color.ImageColor3 = ItemColor
	RewardFrame.Type.TextColor3 = ItemColor
	RewardFrame.EquipButton.ImageColor3 = ItemColor
	RewardFrame.SellButton.ImageColor3 = ItemColor
	RewardFrame.CloseButton.ImageColor3 = ItemColor
	RewardFrame.Type.Text = Rarity.GetTypeByID(Item)
	RewardFrame.ItemName.Text = game.ReplicatedStorage.Items[Item].ItemName.Value
end

script.Parent.RewardFrame.CloseButton.MouseButton1Click:connect(function()
	Access = true
	Available = true
	script.Event:Fire(_Type,_Amount,15)
end)

SkipButton.MouseButton1Click:connect(function()
	Access = false
	Available = false
	Actions(_Timing)
end)

In this clip on the third time you can see when it loops it http://gfycat.com/gifs/detail/MammothNegativeFantail
