Thanks for the suggestions Mark.
My problem is that the trigger works in other sports as well as American Football. Another trigger works in Soccer. I realise that a solution would be to run a separate instance of mfp for soccer only (hate using the term soccer BTW but for sake of clarity I,m using it here!) but I already run multiple instances and I get stability issues if I add another.
I was hoping there might be an excel style IF statement I could use along the lines of if market_name contains "American" then bet, but its beyond me to work the syntax of that out.
