The problematic line is Template.main.helpers as hinted by the error message.
This happens because you do not have a main template. Either create one with the html you want, it should be inside a <Template> tag:
<Template name="main">
<!-- HTML -->
</Template>
Or you can change the Template you are targeting to Template.body since the helper you are using is currently located in your body.
Relevant tutorial part:
Everything inside tags is compiled into Meteor templates, which can be included inside HTML with {{> templateName}} or referenced in your JavaScript with Template.templateName. Also, the body section can be referenced in your JavaScript with Template.body. Think of it as a special "parent" template, that can include the other child templates.
