Getting "NoTemplateError: Could not find template" with backbone.marionette - backbone.js

Question

In this coffeescript+backbone.marionette application I am trying to write, I am getting a "NoTemplateError: Could not find template: '#second-template' when I try to display a different view in my content region.
Here are the two pieces of code, which are based on David Sulc's Backbone Books tutorial. The WelcomeApp displays fine but when I click the menu item that then calls MyApp.SecondApp.display(), I get the NoTemplateError.
window.MyApp = MyApp = new Backbone.Marionette.Application()
MyApp.addRegions
menu: '#menu'
content: '#content'
class MyApp.MenuView extends Backbone.Marionette.View
el: '#menu'
events:
'click #get-second': 'showSecond'
showSecond: ->
MyApp.SecondApp.display()
MyApp.vent.on 'welcome:rendered', ->
menu = new MyApp.MenuView()
MyApp.menu.attachView(menu)
MyApp.WelcomeApp = do ->
WelcomeApp = {}
class WelcomeLayout extends Backbone.Marionette.Layout
template: '#content_welcome-template'
WelcomeApp.display = ->
WelcomeApp.layout = new WelcomeLayout()
WelcomeApp.layout.on 'show', ->
MyApp.vent.trigger 'welcome:rendered'
MyApp.content.show MyApp.WelcomeApp.layout
return WelcomeApp
MyApp.SecondApp = {}
class MyApp.SecondApp.WelcomeView extends Backbone.Marionette.ItemView
template: '#second-template'
MyApp.SecondApp.display = ->
welcomeView = new MyApp.SecondApp.WelcomeView()
MyApp.content.show welcomeView
MyApp.addInitializer ->
MyApp.WelcomeApp.display()
My templates are simply script blocks in the index.html. I actually swapped the template used by the WelcomeApp with that used by the SecondApp and the WelcomeApp can find '#second-template' fine when I do this.
I tried this with both backbone.marionette 0.9.10 and 0.9.11.
Any help here would be greatly appreciated!

Thanks to both commenters on my question. While working to strip down the HTML and coffeescript code, I noticed a div in my HTML that was incorrectly closed using <div>. Once I fixed that to a </div> everything worked. Stupid error but I was just not seeing it until I strip down the HTML enough that it was right in my face. I need better syntax checking.
