Can someone help me on how to make a textlabel tell how many assets you have left?

So, I am working on one of my old games. I work on a lot of games at the same time. But, anyways, here is my question: So, you know how in some games, there is a loading screen, right? And, somewhere in that loading screen is a TextLabel. That TextLabel tells you how many assets you have left, until the loading screen goes away using Tweening. I don't know how to make that. Can someone please show me how?
