Subject: problem with tutorial #2

thank you for your ears and quick responses (especially Paul Caplat and clp).
I'm trying to complete tutorial #2, and keep running into a problem on step 8: simulating the model.
If you look on page 23 of the tutorial guide, there is a screen that shows after you click on "initialize." I am missing a couple of probes "--------", and "Forager >> energy". I don't know why this is, given that I followed all the steps up until this point, including creating probes. Another difference on this screen is that it shows "init" as an init method on my screen and not in the tutorial. Everything else is the same.
After this, I choose "step" and I get an error: "Unhandled exception: message not understood: #self." When I choose the debug option, this is the section of code that's highlighted: "raiseSignal". In the upper box, "Float (Object) >> doesNotUnderstand:"is highlighted.
Are there any ideas for things I may be missing? Where should I be looking for errors?
thanks again
