Rand will generate the same random numbers every time. In this case were using your computers time.
And every time you loop your system time is different So your numbers from say 3:43:01 to 3:43:02 will be different. Random enough for most applications.

That’s where I learned thatEwwww thats got problems try this

This is the way I was going-
