Thanks for letting us know of the wrong screen shot, will get that over to be sorted out. Also made me notice a few other screen shots are not correct either
regarding what you want, have a look to this page
look at section 22 screen shot (they are referring to different stage names but that is what you should be seeing here). having selected ‘special’, then select the Form-Stage and ‘OK’ , then ‘add line’, set the condition to = and then in the TEXT field, type in the name of the stage (approved), then ‘add line’ , set that condition to OR and then repeat to add in ‘Rejected’.
