Automate backing multiple selections, can't find the settings I need

[robbed]

Hi,

I want to automate the following;

Back x number of horses in a race.

Criteria

• If only 1 of the selections runs (all others are non runners): back between 2.0 to 10.0

• If multiple selections run: if "number of selections/number of runners" is less than 50%, then back between 10.0 and 25.0 otherwise no bet

Hope someone can help with this.

Thanks
