=IF(W!Standard_File_Wood_Drawer_Slide_Selection="Grass Dynapro 16",21,20) is the formula for our Max File Drawer Depth in our Global Variable file.  I need to change this so that, if the drawer slide is Grass Dynapro 16 or Grass Dynapro 19, 21,20).  I can't quite get my head around the syntax to add the "or Grass Dynapro 19" to the formula.  If anybody can point me in the right direction, I'd be grateful.  Also, if there is a good reference for this syntax, I'd be grateful learning that too.
