Anyone know what’s wrong with this haml that it’s not displaying a chart  
(= @chart)?

```
%table.body-layout
      %tr
        %td{:colspan => 2}
          .panel#students-chart
            %h3.header Students
            #pieChart.content
      - content_for :javascripts do
        = @chart
        %td
          .panel#activity-chart
            %h3.header Activity
            .content

```

Thanks for any reply.

What kind of variable is @chart?

If I do this, it renders chart as text:

```
            %h3.header Students
      #chart-container
      - content_for :javascripts do
      = @chart
        %td

```

I had this problem before and it was related to indentation and haml.

The question about what kind of variable @chart is will be crucial in  
getting you any help. Also, it appears you might have intended = @chart  
to be indented beneath the content\_for block, but it isn’t.

You might want to join the haml mailing list on Google G. for quick
