Help with WebcoRE piston

Hey all, I’m fairly new to WebcoRE but I have successfully created many pistons that are all working great except for ONE. I am really struggling to figure out why. Hoping someone can help. It’s a pretty simple piston - upon arrival of one of us, presence automatically unlocks our back door. Presence is working, because our nofitcation pistons of arrival are firing, but for some reason this is not. I’m also not understanding the logs, exactly which condition number matches to what line in the code. Any help would be greatly appreciated!

If you enable the trace button, the logs will begin to make more sense :slight_smile:

Ahhh, thanks so much! That was very helpful and I was able to get the problem resolved!
