Measurement Widget Help

BrianPaulson1 — Fri, 30 Jan 2015 19:16:10 GMT

I am trying to insert the measurement widget to a project I am working on. Below is my project code from another example. How do I get the measurement tool added to the map? I have followed the example here:Measurement | ArcGIS API for JavaScript , but I must be doing something wrong since the tool doesn't load. Sorry I am a new to arcgis javascript and I am probably missing something basic. Thanks
