Replicate BF Auto on BD with XL

[Lambretta]

Despite best efforts and endeavour, (concatenate, etc) I've not been able to reproduce what I use in Guardian for BF via spreadsheets in the Betdaq version.
What I'm trying do is;

Place a lay bet
Place a lay bet at 1 second before scheduled off time
Place that bet at a price equal to or less than 34
Take SP only if the price is equal to or less than 34

That's it. But, like I said, I can't structure it in an effective way. Sincerely hoping someone can point me in the right direction.

Thanks.

So, I'm guessing this either has everyone else foxed or people are thinking "Come on, Lamb, you dozy f*ckwit. It's not that hard." Either way, I'd be grateful for input.

Cheers.
