why is this a comile error

I am doing a tutorial from the Thomas~Hansson book and am getting this
error:

Extracted source (around line #17):

14: <%= link_to 'Add to Cart',
15: {:action => 'add_to_cart',
16: :id => product },
17: class => 'addtocart' %>
18: </br>
19: </td>
20: </tr>

Trace of template inclusion: /app/views/store/index.rhtml

I've compared what I have with the book and they seem the same. I'm
thinking that either I'm missing something (very possible) or maybe the
error is actually being generated somewhere else but I'm very green (a
newbie)...

Does anyone have any ideas?

This is better posted to the Rails list:

You are missing one character from the book. On the last line it's
":class", not "class". The latter is a reserved word in Ruby with
special meaning, thus the problem.

Hope that helps.

Is it, this time?

I know this has become our standard response, but the issue above is
a Ruby syntax mistake. It has nothing to do with Rails. Is that not
squarely in our area of expertise here?

I'm not trying to be argumentative. I'm honestly trying to
understand when we should forward them and when we should not.

By the way, you will be doing yourself a service to get a text editor
that includes syntax highlighting for Ruby and rhtml. Little mistakes
like this will be much easier to spot.

I know jEdit, Textmate and RadRails all support rhtml highlighting.

As well as the closing brace after 'addtocart'

No, I don't think so. Here's the call again:

Don't let that second Hash argument throw you.

Speaking of which, I'll have to get a multimode.el for XEmacs somewhere.
Making rhtml-mode shouldn't bee too difficult.

Yes, it's a Ruby syntax mistake. However, it's *not* code that's
runnable without Rails.
