How do I choose the way I loop through a dictionary?

[tuxe_t (Tuxe)]

So I have these rarities:

local TowerShop = {

		["Common"] = {
			["Cameraman"] = {
				["Name"] = "Cameraman",
				["ImageAsset"] = "http://www.roblox.com/asset/?id=14619514318",
				["Rarity"] = "Common"
			},
			["Speakerman"] = {
				["Name"] = "Speakerman",
			["ImageAsset"] = 'http://www.roblox.com/asset/?id=14629729018',
				["Rarity"] = "Common"
			},
			["Camerawoman"] = {
				["Name"] = "Camerawoman",
				["ImageAsset"] = "http://www.roblox.com/asset/?id=14645422989",
				["Rarity"] = "Common"
			}
		},

		["Uncommon"] = {
			["TV-Man"] = {
				["Name"] = "TV-Man",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14650104436",
				["Rarity"] = "Uncommon"
			},
			["Saw Cameraman"] = {
				["Name"] = "Saw Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14644414916",
				["Rarity"] = "Uncommon"
			},
			["Large Cameraman"] = {
				["Name"] = "Large Cameraman",
				["ImageAsset"] = "http://www.roblox.com/asset/?id=14640417457",
				["Rarity"] = "Uncommon"
			},
			["Scientist Cameraman"] = {
				["Name"] = "Scientist Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14650406379",
				["Rarity"] = "Uncommon"
			}
		},

		["Rare"] = {
			["Dark Camerawoman"] = {
				["Name"] = "Dark Camerawoman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14645735472",
				["Rarity"] = "Rare"
			},
			
		["TV-Woman"] = {

				["Rarity"] = "Rare"
			},
		},

		["Epic"] = {
			["Large TV-Man"] = {
				["Name"] = "Large TV-Man",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14649117352",
				["Rarity"] = "Epic"
			},
			["Large Scientist Cameraman"] = {
				["Name"] = "Large Scientist Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14651237390",
				["Rarity"] = "Epic"
			}
		},

	["Legendary"] = {
		
		["Ninja Cameraman"] = {
			["Name"] = "Ninja Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14656701597",
			["Rarity"] = "Legendary"

		},
		
			["Titan Speakerman"] = {
				["Name"] = "Titan Speakerman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14619521972",
				["Rarity"] = "Legendary"
			},
			["Titan Cinemaman"] = {

			["ImageAsset"] = "http://www.roblox.com/asset/?id=14680941942",
				["Rarity"] = "Legendary"
			},
			["Titan Cameraman"] = {
				["Name"] = "Titan Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14646762813",
				["Rarity"] = "Legendary"
			},
			
			
		
		},

		["Mythical"] = {
		["Upgraded Titan Cameraman"] = {
			["Name"] = "Upgraded Titan Cameraman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14619758161",
			["Rarity"] = "Mythical"
		},
		["Upgraded Titan Speakerman"] = {
			["Name"] = "Upgraded Titan Speakerman",
			["ImageAsset"] = "http://www.roblox.com/asset/?id=14619758161",
			["Rarity"] = "Mythical"
		}
		}
}



return TowerShop

I want it so that when I loop through them to create a Gui, it goes common, uncommon, etc, in the way I ordered it. But its totally random, how do I solve this?

Ok I just added a new property to each index called, “Chance” and set it to the rarity, like 50%, 10%, etc. Then I just set the layout order to the chance so the gui goes in order.
