Powerpoint Jeopardy - Hyperlinking Buttons

Hi,

I am creating a jeoprady game for the plant I work at in order to review some key points the employees may have forgotten during the holidays. I have the powerpoint all set up with hyperlinks from the main page to the corresponding questions and vice versa.

The problem I am having is that when I return to the main table from a question I want it to either hide the button for the question or change its color so we know that the button has been clicked. I know that if I make the text in the button hyperlinked instead of the actual button it will change the color of the text but I wanted the button hyperlinked. I was wondering if there is any code in visual basic that I could use to hide the button after its been clicked. Thanks for your help.

if the button clicked event is reached, but im not sure if it is with a hyperlink.

VB Code:

button.visible = false
