Hello. On Step 5, I'm getting the following error in my console:

TypeError: Cannot read property 'push' of undefined
at Object.WatchlistService.WatchlistModel.addStock (watchlist-service.js:24)
at Scope.$scope.addStock (watchlist.js:28)
at angular.js:10903

at HTMLButtonElement.<anonymous> (angular-touch.js:440)
at HTMLButtonElement.jQuery.event.dispatch (jquery.js:4435)
at HTMLButtonElement.elemData.handle (jquery.js:4121)

I've followed the code as the book details, so advice would be much appreciated.

Thanks.

Ugh. I figured this out, for future reference: Several hours debugging later, I finally tried deleting and then re-adding all the titles in the watchlist, like Technology, Financial, etc. Now it works! Again, ugh.

Same thing for me. Delete and recreate and the issue resolved.
