Percentage randomizer picking only rare and uncommon every time

[Waffle_Gamer6 (DevOrange)]

I made a percentage randomizer for a extremely basic case opening system but every time the function picks a random object, it always goes for 2 when it should be 1 and its always rare and uncommon. never common. This is the script:

function buy()
	
	local random_number = math.random(0, 100)
	
	if random_number <= 0 then --70%
		print("common")
	end
	if random_number < 70 then --25%
		print("uncommon")
	end
	if random_number < 95 then --5%
		print("rare")
	end
	
end
script.Parent.MouseButton1Click:Connect(buy)

as you can see, very basic and very annoying why it does not work. no errors are found in the output

If you know what’s wrong, please let me know.

You are checking if random_number is less or equal to zero, which is a really low chance.
You would probably want to do something like this; Checking for greater than (>) rather than less than (<), and starting with the rarest and moving your way to the most common.

if random_number > 95 then --5%
	print("rare")
elseif random_number > 70 then --25%
	print("uncommon")
else
    print("common")
end

oh, my mistake that explains the only rare and uncommon. I forgot to change the symbols as this script was part of another I had in the game but I still have doubled selection

edit: I added the “elseif” and “else” and this stopped the multiple selection. thanks for the help!
