Hi there,

in which tutorial did you read this?
When did you download your shoes version/e.g. which version is it?

This should work with the 1.9 distribution of shoes or recently compiled version with ruby 1.9+

The problem seems to be that it's executed with ruby 1.8 and therefore has to be:

stack(:margin => 8) {

Cheers,
Tobi
