Transferring Variables Through Different Code Sections

Hello I am working on a game where you zap aliens. I wanted to set a variable to detect how many aliens are left, but because each alien has its own Co-Block section it wouldn’t change the variable. Does anyone know how I can make this work? Have a good day and thanks for reading.

Ok guys I fixed it I ended up hearing about a “Global Variable”, and I said “That might work for me.” Anyways, I ended up creating a Cospace property and I just changed that. Thank you for anyone who viewed or tried to help I really appreciate it! :smile:
