Lay to fixed liability

Sorry for being really thick, but I just want to set a simple trigger to lay to a fixed liability & I can't work out how to do it! Any help would be great. Thanks, Christine

To lay to a fixed liability the formula is

liability/(lay odds - 1)

100/(4.1 -1) = 32.26
lay 32.26 @ 4.1 gives £100 liability

Also for backing

liability/(back odds - 1) would win £100

Thank you elite... just what i was looking for

Laying to fixed liability of say £50 would be, in the Amounts section 50/(lay_size-1)
Backing to win fixed amount of £50 would be, in the Amounts section 50/(back_size-1)

Nice one, thank you

Please Ignore Above Post incorrect

50/(lay_size-1) is the current default lay, which is not suitable here

correct version is:
For fixed lay liability of £50 on any odds ... 50/(lay_price-1)
For fixed Win amount of £50 on any odds .... 50/(back_price-1)

So for example: fixed lay of £10 on probably loser ... 10/(lay_price-1)
