Why is this embedded ruby code evaluating to nothing?

This code here:

<%= case event.subject.value
        when 1
            puts " upvoted"
        when -1
            puts " downvoted"
        when 0
            puts " removed a vote from"     
    end %>

does not result in any string being rendered. I tried adding an else statement just in case event.subject.value had a different value from 1, -1, or 0, but the code still evaluated to nothing. The code throws no errors...

Ok I realized what the problem was. I had to remove the puts from the switch statement.

puts returns nil. It's side effect is that it outputs to the stdout.

"puts" method outputs to your console( server log ), did you try to remove puts?
