title: Conditional use of $ on summary field
body: <p>My summary field displays dollars. If the value is zero, I want to display a dash without the $ symbol. I currently have in the custom style settings to Show Zero Values as a "-", however, what I get in the report is "$-"</p>
  
  <p>I see that there is a conditional formatting option, but I'm not sure how to refer to the summarized field in the code. How can I accomplish this?</p>
