In-play football betting using overs and time played

Hi, how would I place the IP bet to bet on 1 more goal please? For example if the score is 2-1 how would I place a bet on over 3.5 goals?

Additionally, can I trigger the bet after a certain time period, for example only bet if the game is 60 minutes old or more?

Many thanks, Mark

Hi
The trigger conditions will be:

markets betting code is over/under (soccer) market_score1 + market_score2 + 0.5
and selections index is equal to 2
and selections trigger expression match_minute is equal or greater than 60

this will place a bet on Over (index 2) in the current OU market
all the over/under markets for the game need to be in my markets and refreshing 

Awesome, thanks so much for the speedy response!
