Excel Automation - Avoiding More Than One Bet

[alnomes1]

Hi all,

I have set up excel automation which is selecting a horse to lay at specific conditions.

I only want to trigger one bet per race but sometimes the condition can arise more than once and trigger a second bet.

I have it set that only one bet per horse can get triggered but my spreadsheet currently enters two bets into the market, instead of the intended one, when more than one horse qualifies.

Is there a safeguard or rule in Guardian that I can set up to avoid multiple bets or do I integrate the rules onto my excel spreadsheet?

Thanks for any assistance.
