"Random" table picker only having out output?

Firstly please use some more variables as you access each the full path for each item. The main problem is the way you have your if statements ie:-

-- badly formated code
if [logic] then
-- code
if [logic] then
-- code
if [logic] then
-- code
end
end
end

-- formatted code
if [logic] then
-- code
	if [logic] then
	-- code
		if [logic] then
		-- code
		end
	end
end

You can see how only your first statement has to be true for the others to run.

Lastly you have a lot of duplicate code and there are better ways of doing this so we only use the same logic but with different information, we could use a table to store our data in:-

Example:-

-- we creat variables so we do not need to access the full path each time
local buyButton = script.Parent
local funds = script.Parent.Parent.Parent.Funds
local cancel = buyButton.Parent.Cancel
local statusTxt = buyButton.Parent.TextLabel
local img = script.Parent.Parent.Image
local skins = script.Parent.Parent.Parent.Parent.Skins
local txt = script.Parent

-- this is our data list so we do not use lots of logic just for checking the same thing
local data = {
	{
		name = 'Blossom Skin',
		img = 'rbxassetid://633409829',
		skinName = 'blossom',
		cost = 24
	},
	{
		name = 'Desert Camo',
		img = 'rbxassetid://633412461',
		skinName = 'desert',
		cost = 24	
	},
	{
		name = 'Carbon Fiber',
		img = 'rbxassetid://633490575',
		skinName = 'carbon',
		cost = 24		
	}
}

local deb = false -- debounce
buyButton.MouseButton1Click:connect(function()
	if deb then return end
	deb = true
	
	local itmData = data[math.random(1,#data)]
	if funds.Value >= itmData.cost then -- check price
		-- proces this random item
		cancel.Visible = false
		statusTxt.Text = 'Processing'
		wait(3)
		if funds.Value >= itmData.cost then -- we have waited so we need to check this value again as it may change
			statusTxt.Text = itmData.name
			img.Image = itmData.img
			funds.Value = funds.Value - itmData.cost
			local skin = skins:FindFirstChild(itmData.skinName)
			if skin then skin.Value = true end -- enable skin if found
			txt.Text = 'Accept'
		end
	end
	
	deb = false
end)

I hope this helps please comment if you do not understand how / why this script works.
