Check if the script is installed correctly by going to your Faction Crimes page and the RECRUITING tab. You should see that the join buttons now have green or red text. Join buttons that are green mean that you meet or exceed the Checkpoint Pass Rate set by your faction for that role. Other buttons will be red. If recommendations are turned on by your faction, the script will also pin a recommended OC to the top of the page with a purple outline for the role it recommends for you.

This script advises you on the attack screen what sort of attack to make (leave or hospitalise) based on settings made by your faction leaders. You will know if the script is working if you see a recommendation on the top of the attack screen (while your faction is in an active war).
