This is what I have got so far but it doesn't countdown.
for i= 1,20 do wait(1) print(i) script.Parent.Text= i end
You're very close. It turns out, there is a way to make for
loop count down instead of up. You use the third, optional argument, which is how much is added to i each time the for
loop runs. By default, this is 1. But if we set it to -1, it will cause the loop to count down.
for i = 20,1,-1 do --code end
