hi
you got in just before me mark,BUT you misted the record 1 minute before the start.
here is my trigger
in the constants set
your bet amount
the time before the off to record the first 3 favourites
the first trigger records the first 3 favourites at 1 minute before the off(or the time you set)
then in-play the second trigger places the lay bets on any selection that makes first favourite but is not one of the recorded selections
