hi
the best way is to add the condition
and selections (back matched or lay matched you did not say what the first bet is) is equal to 0.
so for a back bet then geern up, you would have
and selections lay matched is equal to 0
this way the green up will only green up if there is no distribute loss or green up bet fired.
as for your conditions that you have tried, if your triggers have a close block trigger included, then this would reset the green up trigger to 0, when the block closes and restarts.
