Split issue

I’m working on a curve from a top view. All the curves have been drawn on the cplane and yet when I add points or a line I’m unable to split the curve. http://www.screencast.com/t/GdyMIuzy

It looks like you are trying to split a closed curve (circle) with a single point. You need two points or line crossings to split it in two.

That was the problem. Thanks Max. Bit by bit I’m learning to use this thing.
