Help with not taking payment when action is cancelled?

Hi, I have a simple mod that charges the player to go into CAS to make an outfit, but I wanted to ensure it does not charge the player if they cancel this action (i.e. hit the x button). At the moment I believe the payment is taken at the beginning of the interaction, and I have tried variants of 'timing t="at_end"' but to no real luck. Any ideas?
