Can someone tell me why this produces true (1) instead of  false (0)?

  (Ref(Fml( "Div(up3=div)RfMMO 1&FO"),-1)=3 )     (false)
OR 
 Ref(Fml( "FO Cross" ),-1)=1                                (true) 
 OR
 Fml( "Div(up3=div)RfMMO 1&FO")=3                    (false)
OR 
 Fml( "FO Cross" )=1)                                          (false)

AND

 (Fml( "Rf EntranceSignal #1" )>3                          (false)
OR
 Fml( "Rf EntranceSignal #2" )>1                            (false)
 OR                   
 Fml( "Rf EntranceSignal #3" )>0)                            (false)


I  have one (true)  before the AND & all   (false) after the AND
My thinking is the AND means both must produce true results for the answer to
be true.

Thanks for anyone who can straighten me out on this
