Tutorial three css file doesn't compile properly #63

Steps to reproduce error

Clone the Pollen repo and start a server in the third tutorial directory:

$ git clone https://github.com/mbutterick/pollen.git
$ cd pollen/scribblings/third-tutorial-files/                                                                                
$ raco pollen start

Thanks for the bug report. Reproduced & fixed.

It usually takes a half hour or so for the Racket package server to notice an update (and make it available through raco pkg update ...). In the meantime, you make the tutorial work by going into styles.css.pp and changing ◊(define multiplier 1.3) to ◊(define multiplier "1.3").

Thanks! Sorry I couldn't debug this deeper myself; the error message was, let's just say, uninformative…
