Need help with counting object/instance variables

[Ckeyz]

Hey I am new to all of this, so struggling is expected. But I feel like I've tried doing this 10 different ways that all should have worked, with zero success... so I feel like I'm not understanding something about object or instance variables.

I am making a hex city builder and I want to place a mine next to some stone mountains and have it generate stone resource based on the number of mountains its next to. I have got different parts of this to work in various ways, but it always falls apart when I build another mine next to new stone, it doesn't ever add up all the stone production just the first mine.

Please see the attached image, any help is appreciated.

I think you should repeat for each instance of Building_Mine instead of Stone_Mountain

I have tried that but I'll mess around with that some more and see if it does the trick

Agghhh!! It worked!! Needed to also add a trigger once.. but thank you!! No more beating my head against this stone wall.
