Poker trigger help

Hi.

I would like a little help here...
I need to skip a bet in a poker game if two or more selections have the same price (back and lay) so it can avoid tie dead heat results.
Thanks.

Hard-coded way:
Trigger Expression IF(OR(s_1_back_price=s_2_back_price,s_1_back_price=s_3_back_price,s_1_back_price=s_4_back_prices_2_back_price=s_3_back_price,s_2_back_price=s_4_back_price,s_3_back_price=s_4_back_price), 1,0) is equal to 0

Right way:
1. Create a trigger variable
2. every round set it to 1 if
Any Other Selection's Back price is equal to back_price
3. Check it in betting trigger.

Thank you very much Tim.
