Creating First Custom Application- Map/Layer Issues

Question asked by jfarmer@cityofstafford on Oct 2, 2013

We recently got a web host and cloud storage so I am working on creating some custom applications using ArcGIS API for Javascript. I have played around with the basemap gallery sample (https://developers.arcgis.com/en/javascript/jssamples/widget_basemap.html) but instead of creating a new map, would like to use an existing webmap or separate layers.

I used this code to try the webmap with no success, I just get a blank screen. Also, if I just want to use feature services, how do I add those in to a new map?

Thanks for your help! I'm sure it's obvious I'm a newbie to this.
