Where on Fitday is the recommended sodium number? Mine just says "-----"

. I've only been using Fitday for a little over a week (contemplating moving to the PC version, but for now using the online version), and for the past week my average sodium was 1775.
How/where can I find the recommended?
Edit: Whoops, I mis-read. I get it now. Sodium for adults should be no higher than 2400. I assume, the lower, the better.
