Warped text in PS CS6

[DougStocks]

I need help in typing text along a curved path in PS CS6. I have watched and read several on-line tutorials and they all seem to say about the same thing and seem pretty simple. I create a path using the pen tool. Next I select the Type tool. I position the cursor over the path where I want to start typing. The cursor changes to show the little curved line. I left click once. A bar perpendicular to the path appears. I start typing and nothing appears. I think I have the font size & color properly selected, because I have no difficulty in typing text in a text box. Any idea as to what I am doing wrong?
