problem from a beginner

[Alan Kay]

Hi Mark --

You need to return the value of answer.

You can do this by adding

        ^ answer.

at the end of the method.

(Don't forget to put a period between the "]" and before this line.)

Having said this, let me refer you to http://www.squeak.org. This 
site is for people who program in Squeak proper.

This http://squeakland.org site is for teachers, parents, and others 
who are working with the etoys part of Squeak for children.

Cheers,

Alan
