Variable syntax in controller

Question

Should be a simple question, but I'm a Rails novice and just kinda hacking this together. What's the format to add in a variable to this syntax? Pseudocode:

 $var = '<html>' . $var2 . '</html>';

Except in ruby...

class PdfController < ApplicationController

  def index
    @html = %Q{
      <html>
      VARIABLE
      </html>
    }
  end
end

You can use Ruby interpolation:

class PdfController < ApplicationController

  def index
    @html = %Q{
      <html>
      #{ VARIABLE }
      </html>
    }
  end
end

It's worth nothing that any valid Ruby expression can go in the interpolation braces, not just variables.
