condition help please

Hi,
Having a problem creating a condition to prevent a trigger from firing.
In laymans terms
if selection name is same as last name and less than 1.7 for both bets ... don't fire.  
examples:
3.70  5.00  Nadal
1.65  5.00  Nadal        trigger okay to fire

1.65  5.00 Nadal
1.62  5.00 Nadal         trigger not okay to fire.
Thanks for your assistance

Hi
Try the following (untested) condition block:
AND NOT
            selections trigger expression bm_1_backp is less than 1.70
            and selections trigger expression bm_2_backp is less than 1.70

Hi Mark,
I think I may have found an alternative way during the early hours of this morning.
It seems to be working but will test run your recommended conditions should it fall apart.
Many thanks once again.
