I'm trying to figure out how to use the type on a path tool in Illustrator.
I used the curvature tool to draw a wavy line, which I now want to type on.
I keep getting a message that I cannot make any sense of. It reads:

> INSIDE A PATH.

I have seen [this post](https://graphicdesign.stackexchange.com/questions/16239/adobe-illustrator-error-creating-text-constrained-by-shape-area-type-tool?newreg=3e5fd902b9ca4b53865a1c1640063e6c), which describes the same problem, but I tried the answers suggested and they're not working. I wonder if something has changed in illustrator since this question was last answered?
