text in a shape problem.
I'm trying to type text in the shape of a heart. I have followed the tutorial by creating the shape and then selecting the text tool, making sure I am on the horizontal type tool. When I hover over the shape (i am on the shape layer in the layer palette) I do not get the cursor with the circle. outside of the shape I have the cursor wit the box, on the edge of the shape I get the cursor with the squiggly line, but it won't give me the circle to enable me to type in the shape of the heart. any suggestions?
thanks in advance!
