Just learning smalltalk & squeak. One of the first things I wanted to try was to load text into a scroll morph at the press of a button.

I renamed the Scrolling Text morph scroll.
And I put the following code underneath button.
Everything seems fine but the last line

The error I get back is that scroll is an unknown variable.

So my question is am I referencing the scroll morph correctly in the button script?

button
   | stream data |
   Transcript show: 'hello'.

"Read file into a string"
   stream _ FileStream fileNamed: 'test.txt'.
   data _ stream contentsOfEntireFile.
   stream close.
   Transcript show: data.
   scroll setCharacters: data.

Thanks in advance

Steve
