Multilevel lists only go to 9; I am normally doing something that is up to 30 (questions for tests)

I think the answer would just to add levels to the list, but I can't figure out how to do that.

It will continue the number, but the formatting on the everything after 10 is just a little different (after the number, there are more spaces, than on 1-9) that's the only difference, but I just can't fix it.

NEVER MIND - AFTER THREE WEEKS I just found my answer!
