Making a NumberValue is completely unnecessary: just use a for loop:

for i = 5*60, 0, -1 do 
	m.Text = i
	wait(1)
end

To display this using minutes, simply divide i by 60. To get the remaining seconds, use the modulo operator:

m.Text = math.floor(i/60) .. ":" .. i%60

This has a problem, however: seconds less than 10 display only one digit, so let's add a simple if statement:

m.Text = math.floor(i/60) .. ":"
if i%60 < 10 then
	m.Text = m.Text .. "0" .. i%60
else
	m.Text = m.Text .. i%60
end

Or you could use two for loops

Wow! Thanks alot. This will really help me out for my game me and my friend are making! MUCH appreciated!

Whoa, that's really inefficient...

Alright, so to make an efficient timer you would use a for loop:

ti = 120 --Two minutes
while wait() do --A while do loop to repeat the contained code
	for i=ti,0,-1 do --A for loop that goes backwards from 120 to 0
		m.Text = (i.." Seconds left") --Changing the text (I apologies, couldn't make it Minutes:SecondsInMinute)
	end
end

References: For and while loop

Make a value, and do some math

m = Instance.new("Message")
time = Instance.new("NumberValue")
time.Value = "240"
while wait() do 
wait(1)
time.Value = time.Value - 1
m.Text = time.Value .. " Left"

Should work, but it will show the timer in seconds, not minutes and seconds

You forgot to make the Value - 1 every second :)

How would I do it as like 5 mins but when it becomes 5:00 it then becomes 4:59?

Who -1 this? You don't have to -1 this just beacause I'm a begginer, Or made some spelling mistakes. -_-

Well, for one thing, you don't have an "end" for your "while" loop.

So? I dpn't like the reputation thing for scripting helpers

It means you're feeding misleading/unreliable information. ScriptingHelpers is a forum website for scripters to help other scripters. Good answers receive upvotes, bad answers receive downvotes. Hypothetically.

Good try, but your script has a few problems (which I imagine is why it got downvoted): 1. The NumberValue is unnecessary. 2. You say "while wait() do wait(1)", which will actually wait for about 1.03 seconds instead of 1.00 seconds (it should be "while true do" in this case). 3. You missed an "end" to the while loop. ...

... 4. (Minor) Since it's a number, you should really say time.Value = 240, not time.Value = "240" (the latter is a string, not a number, even if Roblox converts it for you in this case).
