If a Yes is selected from Radio button, how do I tell acrobat to go forward three tabs

[Bob24045581wagx]

I have a form that has 4 options for answers to questions.  In some quesions, a yes answer (button 1) will require and explanation.  If the user selects Yes, I would like the cursor to move to the explanation box.  Can anyone provide some way to simply do this?  Thanks in advance.

Put this code in the Mouse Up of the "Yes" radio button.

this.getField("ExplanationBox").setFocus();

the "ExplanationBox" text must be replaced with the exact name of the the explanation box on your form.
