adding direction widget to map

[AlanaD_Andrea]

I am trying to add a direction widget into my current asp.net mvc 4 application. I have a map already created in this application I just need to figure out how to put a direction map tool into it. I am really new to all of this coding and would really appreciate any advice or support. I have been working with this documentation but cant seem to figure out what I am missing. Everytime i add in the code my original map disapears from the site but I get no errors when building the solution. Can someone please help, it would be greatly appreciated.
thank you in advance. here are the links to what i was looking at.

Uncaught SyntaxError: Unexpected token < map.js:127
Uncaught ReferenceError: changeBasemap is not defined localhost:15885/Sentry/:186
Uncaught ReferenceError: map is not defined localhost:15885/Sentry/:111
Uncaught ReferenceError: addTypeSymbols is not defined utils.js:560
Uncaught ReferenceError: addTypeSymbols is not defined


i dont understand how to define my map and get it to display in my application with these direction map tools. Any advice or help would be great...thank u
