Please Help! Keeping Score with multiple items

[micaelayars]

Hello everyone. Basically I am making a game where A plane flies through multiple circles and keeps score based on which/how many rings you fly through. My problem is that I cannot figure out how to keep score for multiple items. I want the score to go up once when i fly through a ring and then go up again when I fly through another. I hope I explained well enough and I really appreciate any help that is offered. Thank you in advance!
