How do you make a message countdown from 1, to 30?

I've been wondering this, for a while so here it goes, is "," the piece of code for doing "To"? Like 1,30 would be like saying count from 1 to 30? What's the coma supposed to do exact? If that's correct, how do you use it for messages, so that it will repeat it from 30, until it gets to 0?

Easy use a for loop

for i = 30,1,-1 do
	m = Instance.new("Message",Workspace)
	m.Text = i 
	wait(1)
	m:Remove()
end


-- the coma just separates the numbers it's something you don't really think about you just memorize it as you go.

m = Instance.new("Message", Workspace) --Labels the type of Message, for a Hint replace "Message" with "Hint"

for i = 1,30 do --This is a for loop, it repeats something a certain amount of times, the , is used for example like the word "to" or a  "-" saying that it will start from 1 and end at 30, 1 to 30 (1-30)
	m.Text = i --Makes the message text the 1-30
	m:Destroy() --After it reaches 30 it destroys itself
end --Ends the loop
