Thanks - got it.
Can't see a problem with the trigger file, although it is a little thin on conditions. I suggest you add a condition:
and Market's Name does not contain "Distance"
You could also make a trigger which will delete those markets before your betting starts.
Also, if you are loading your markets using the Market Locator, add a property:
Market's Name does not contain Distance.
The triggers are shown to operate in Win markets, but in your first post you say only Place markets are loaded?
No problem saving the edited trigger file with the Dist Loss % changed.
Try Saving As ...to desktop just to check it.
