I know (or think haha) I'm doing it the right way, but I still can't. I have a number range from 1 to 10. The reader has to rate his/her day. The numbers are white. When they click on it, it should turn black. On the rollover, it turns black. When you click on it, it turns black. But then it just turns white again. I want the number to stay black. I attached a part of the page. I made a button, just of nr 1. I tested it in Adobe Acrobat PRO and it just doesn't work.
Thank you so much for the support.
