I'm guessing you're using one of the free sheets out there. If a bet has already been placed the bet reference column will have been filled which stops any further bets being placed until that reference is cleared.
You either need to update the sheet to cover those circumstances where you place two bets or use one of the offset triggers so any opposing bet gets placed once the first bet is taken.
