A couple things, probably.

Your client is probably stripping the semi-colon. What client are you in? In short, clients like to use that for command stacking, as in:

foo;bar becomes
foo
bar

That's probably part of your problem.

The period may or may not be right. I'm not familiar with this core, but the core has a chance to modify the string for a program, so that . may be indicating the end, or something. Scroll down a bit further and try the editor, it's like another 4 or 5 lines down. That's supposed to tell you the compiler errors, or at least so the tutorial says.

Are you sure the core you're using is compatible with that? You might also have a look at the moo manual; I don't have a link atm, but it's not hard to find. It'll not tell you about any specific coore, only about what's going on behind the scenes, and it's a bit complicated, but it is useful if you don't know why something is mysteriously failing and is probably worth a look, anyway, to understand some of the internals.

Try the semi-colon thing client-side first, only giong further if that doesn't work: the easiest way is generally to type look;say test and see what happens; you should look and then say test, and not get a typo message or only do one or the other.
