I cant seem to calculate line lengths using the field calculator tool.  Seems like it should be something like this

Of course I was basing this assumption off of a python example (of which I have no idea how to use as well).  I've searched the threads all over but cant seem to find this simple task.  Could anyone enlighten me please?
