I'm using the latest winplace trigger from the library.  What constants and trigger adjustments should be added say that I can adjust the %'s and make the calculations for the following instructions:
Once the lay liability in the win market is known, fire a unmarked back bet in the place market for 75% of the lay stake used in the win market to return 110% of the liability in the win market; 
Only proceed with the calculations for the place marketback bet size and the odds that will be required to cover the liabilities the win market;
Kindest regards,
