Simple Question about code.

[zireko]

I simply want to ask how I would get the frame rate to display in a small window? I currently have this small lua and I'm just trying to call a function. This is my first thing and I'm trying to play around with a very very simple addon. My lua code is listed below.

function GetFramerate(number) 
end

This is the only line of code I currently have and I'm not getting any lua error or anything. But it is not displaying anywhere. Do I need to make a frame for it to display in? If so how would I do that easy methods only please.
