I've made to give a litle solution to mi problem posted a litle down but I don make that when NAV 1 OR APR are selected the different texts appear, my code is: (A:AUTOPILOT APPROACH HOLD,bool) || (A:AUTOPILOT NAV1 LOCK, bool)%( (A:GPS DRIVES NAV1,bool))%{case}%{:0}VOR/LOC%{:1}LNAV%{end}now how works the OR clausule can it give true when the first operator in the stack is 1 and the other 0 and viceversa??Thanks a LotHelio Alberto Regalado Moreira

Try: (A:AUTOPILOT APPROACH HOLD,bool) (A:AUTOPILOT NAV1 LOCK, bool) || Arne Bartels

Hi:Well It did not work at all it only show the text when APR is selected, so as I found out that when APR is active NAV deactive and viceversa, I decided to make a 2nd element exactly equal to the first only that in visible I put only 1 variable.It may not be the optimal but works pretty well.Thanks a lot for everythingHelio Alberto Regalado Moreira
