rules trigger if horse certain age

[bezbublinek]

hi, I am looking for some guidance, rules file about a rule that only triggers if the horse is under a certain age.
For example i create a lay 3rd favourite rule in a market, but id like it to be triggered if the 3rd fav is under 8ys.
so, applies to selection is going to be in position 3rd, sorted in order favouritism,

but i have no idea what is the next step. I cant find age options among the condition type that bet angel allow us to use.
Any advice welcome
Thanks

You first need a 'Set/Modify Stored Value rule applied to 'Every' Selection
It just needs to trigger once and can be 'Always Armed'
Then on the Stored Value tab, use the 'Store Value as Text' option to store the age of the selection

Then on your lay rule that is applied to the 3rd fav add a Stored Value condition as shown below (using whatever name you stored with the first rule above - in my example I used the name 'runners_age'
