How do I prevent multiple arrows from appearing?

Greetings C3 world!

I tested this on my own for a few days and I'm not making much progress. Essentially, I'd like to have this black arrow be on the sprite that you last left clicked. What's happening is if you click sprite A, then click sprite B, multiple arrows show up.

Suggestions on how to prevent this so only 1 black arrow shows? Thank you in advance!!

Instead of creating a new arrow every time, you can just put one arrow instance on layout and set its position to the clicked sprite.
