Within portfolio.ejs, http://twitter.github.com/bootstrap/assets/js/bootstrap-tab.js is broken and nothing happens when the Nockmarket tab is clicked. Has anyone dealt with this or know how to fix it?

While running the Chapter 2 code. I found that the code in func "order" would trade any remainingvolume at the best available opp price irrespective of the actual order price. I am not an expert on "Trading" but based on the write up in the book the price check seems to be missing. I added the following and the code works as I expect it should:

var bestOppPrice = oppBook.prices.peek();
var bestOppVol = oppBook.volumes[bestOppPrice];
if (orderType == BUY &&
bestOppPrice > price) {
console.log("break for buy");
break;
}
else if (orderType == SELL &&
bestOppPrice < price) {
console.log("break for sell");
break;
}

I was going into chapter three changing from the mongolabs to the interal mongo db and got this error, scratching my head wondering what I am doing wrong.
var UserSchema = new db.Schema({

I am getting an error when trying to run the code for Chapter 2 examples. I get down to the last bit of code before adding the priceFeed.js file; basically all of the exchange.js code and when I run the tests they pass but when I run node nockmarket I get the following error:

$ node nockmarket
order { type: 'buys', price: 35, volume: 93 }

35, 93

I am trying to learn node and I am not sure where to even look to debug this code. Just to be sure it wasn't user error I copied the code from the repository and tried again. I'm still getting the error. Please help. Also some guidance on how best to debug this code would be helpful as well (you know the whole teach a man to fish...). Normally I would just use the Chrome debugger to step through the code.

Thanks

I am using Node 0.8.17 if that matters and while doing npm install in main directory of chapter01 after node app.js I get this:

$node app.js
