If wagers allow the customer to make a second wager pending a win on the first selection. If wagers must be made on one call, and the second part of the if wager cannot exceed the amount of the first selection.

For example:

Dallas Cowboys -5 $110 to win $100 IF (if win, tie, or cancel) Carolina Panthers +4 $110 to win $100 If the Cowboys lose, the wager stops there and is scored a loser -$110; if the Cowboys win +$100 the wager continues to the Panthers wager; if the Panthers win, the wager is a $200 winner; if the Panthers lose the wager is a $10 loss.
