Button Cycle Through ASCII Characters?

[Andrew Harvey2]

Hi all,

I'd like to create a cycling three-state radio button for a form inside Acrobat DC.

Like this: (any characters would do, but this would be ideal)

I have found a thread here, which gives an example of a script to do this:   [Javascipt for Tri State Button Please Help ]

However, when I dump these examples into the script section of a radio button's properties, it does nothing.

Any other threads I can find either don't have solutions, or reference the thread above.

Any help would be hugely appreciated!

The example uses buttons, not radio buttons.

Thanks very much, that was an obvious mistake on my part.
