Numbered level names

there are sequential level names like this: 1,2,3,4…999

how can i run this level when every chapter passes?
I did as below but I’m a bit of an amateur. I just started programming.

Thank you

What do you mean by “when every chapter passes”?

For example, when the user finishes the level named “1”, level “2” will start.

I found solution: every level I have to make world settings. I gonna duplicate one map for new levels.
