In-app purchase piad subscribe problem

Hello everyone(sorry for my bad English). I have registered a product as a “paid subscription” but I don’t understand how to check if there is an active subscription or not. I tried to use the “watch the event:” owned “” action but it doesn’t seem to work. Anyone know how or have any ideas?

You should check this out

Thank you for your answer. I tried to set everything as in the video but I still can’t get a variable or anything that tell me when there is already an active paid subscription. Did you know how to do it?
