Formula Designer Fundamentals
          The Formula Designer (FMD) fundamentals include access to the function and a description of the window layout.
         
         You can access Formula Designer (FMD) from the main SunSystems navigator window.
The Formula Designer (FMD) window is split into three areas which are resizeable:
- Formula Variable pane
 - Formula Edit area
 - Formula Display area.
 
Once Formula Designer (FMD) is open, the Formula Variable window is populated with variables which are displayed in a tree-like structure.
