Change size over time

Hi guys! I need your help :wink:
I’m doing a little project for school and have to do a top down “level” where on right mouse button I spawn a cube, that have to grow 3 seconds then destroy. I’m almost done it. I can spawn cube, make it disapear after 3 seconds, but don’t have any idea how to make it grow. Second problem is that when I spawn more than 1 cube only last spawned disapear. Can you help me? :slight_smile:
