Accessibility for button.

Hello All.

I have a button that repeats a subform when clicked.  Everything works just fine, with one exception, screen readers only read the button's caption "+" and not the custom text.

Using the Accessibility Pallette I typed an explanation of what the button does when pressed in custom text and in tool tip.  Then I set screen reader precedence to "Custom Text".  However, the screen readers (JAWS and Thunder) only read the "plus" and not the custom text.  Am I missing something? 

For now I've added to custom text to the button's caption along with the "+", and made the font size 1 and the same color as the button.  I really don't want to do this for all of the buttons.

Your suggestions and help would be greatly appreciated.

I'm using Windows XP, LiveCycle Designer 8.2, and Adobe Pro 9.

Thanks,
