Hello I am reading Agile Web D. with rails (third addition). And I need some help with it. I have reached chapter 9.3 when I press on the add to cart button I get an error message. a real ugly one. eventually, I downloaded the PDF version and copied the content of the files but it did not help. I have looked but could not find the problem. Please give me a hand. Thanks Angel try { Element.update(“cart”, "\n\n\
Your Cart\n \n \n\n\n\n\n \ \n\n\n\n\n\n\n\n \n \n $209.65\n\n\n\n \n \n $209.65\n \n\n | 7× | Pragmatic Project Automation | | Total | \n\n \n"); $("current\_item").visualEffect("highlight", {"endcolor":"#114411","startcolor":"#88ff88"}); } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('Element.update(\"cart\", \"\\n\\nYour Cart\\n\\n \\n\\n\\n\\n\\n \\n\\n\\n\\n\\n\\n\\n\\n \\n \\n $209.65\\n\\n\\n\\n \\n \\n \\n \\n\\n | | | | 7× | Pragmatic Project Automation | | Total | $209.65 | \\n\\n \\n\");\n$(\"current\_item\").visualEffect(\"highlight\", {\"endcolor\":\"#114411\",\"startcolor\":\"#88ff88\"});'); throw e } ---

Hi, this is a Ruby mailing list (the language Rails was written in), not a Rails mailing list. You should try a Rails list, you will get much better help. Especially considering the code you posted looks like JavaScript, not Ruby. A few things, though: 1. If you are certain you’ve done everything correctly, you might check the errata to see if something in the book isn’t right: [Pragmatic Bookshelf: By Developers, For Developers](http://www.pragprog.com/titles/rails3/errata) 2. You said “when I press on the add to cart button I get an error message. a real ugly one.” but you haven’t given any information about the error message. These exist to let you know something is wrong, and where it went wrong so that you know where to go start troubleshooting. This would be good information to include, it gives people (and you) an idea where it went wrong. ---

Thank you for replying. the application is written in Ruby. the error message is something I do not understand. the link to my files is at: Download link: [http://rapidshare.com/files/389266124/chapter-9.tar.gz](http://rapidshare.com/files/389266124/chapter-9.tar.gz) [http://localhost:3000/store](http://localhost:3000/store) I am certain that I did something wrong, I just can’t seem to find what… the ugly message I got is the code I attached in my first message.

Regardless of the application being written in Ruby, Rails is a huge and separate project from Ruby and thus requires its own mail list. It looks like you are using ruby-forum to access the mailing list, so just look a single link down on the main forum list. Here, I’ll even give you a direct link there… [http://www.ruby-forum.com/forum/3](http://www.ruby-forum.com/forum/3) > the error message is something I do not understand. Yes, but without the error message no one is going to be able to help you. > [http://localhost:3000/store](http://localhost:3000/store) Localhost is local, only you can access it. -Jonathan N.
