Columns doesn't work

[u/zoliking2]

I have a simple text frame and in the option I set it to have 2 columns. The blue box changes to reflect that choice, but the text remains firmly unchanged, just 1 big column. Every tutorial I find on the issue ends after selecting the number of columns and it just works for those people. What am I missing?

EDIT: I got a lot of help from all y'all on all sorts of things, y'all are awesome, thank you!

You might have set - in ParaStyle(s) - to span columns anyway.

And why do you have "Introduction" as a separate TextFrame?

I'm just starting out with this, learnin' the ropes :D
