Photoshop: writing on a curve Options

[*mona lisa*]

In Photoshop, you know how you can write on a curve? You make a path using the pen tool, and when you put the type tool cursor on top of it, the cursor changes and when you click, you can write on the shape of that path.
I tried to do it, but it's not working for me. Anyone know why? or how i can fix it? thanks, any help is appreciated because i know a lot of people wouldn't know.

To put text on a path, you first need a path, obviously. Choose the Pen tool, shape tool, or line tool. Next go to the options bar and make sure the "paths" option is active, then create an open or closed path.

Once your path is created, switch to the horizontal type tool. Bring your cursor close to the path, and your cursor will change slightly, and the status bar will change to say, "Click to create type on a path." Click, then type... that's all there is to it! Well, you do have to click the commit button to accept the text.

whenever i put the horizontal type tool on the path, the cursor never changes.
