Trigger once doesn't work :(

So, I’m trying to deduct a variable’s value only once, that’s why i’m using the trigger once, but it seems to enter in a loop, like it’s deducting the same value all the time, staying all the time the same, without adding any value to that variable. Any ideas why could this happen? :open_mouth:

Trigger once only means “trigger once when the condition is true”. The event will trigger again if the condition becomes false and then true again. Most likely that is what is happening in your event. You can post screenshots of the event if you need a more detailed comment.
